We have made Patreon ( www.patreon.com/FishBumpTv ) available for members who are interested in consultations on their projects. Thank you for your support!
This information is absolute gold. There are tons of boat repair videos on CZcams but none presented so clearly and comprehensively. There will be people referencing these videos prior to attempting a repair for years.
Wow, thank you so much! We hope to do a lot more with the channel as it grows. Everyone's support and encouragement is much appreciated!
Hope you don’t mind I threw up a link to your channel on thehulltruth. I’m sure being in the boating industry you are familiar with the site!
Solid comment brother. Couldn't agree more. Such a down to earth no nonsense guy full of experience and knowledge. Can't buy this stuff. Very glad we've all found it. Amazing. So though and so much experience.
this channel is like South Main Auto for boat repair lol (if you don’t know who that is and are into car repair I highly recommend it)
@@Art-jw8ho Thanks! I will have to check them out.
Capt. Joe, don't worry about the videos being too long. This is a very useful video that can apply to every boat owner making minor repairs to his own boat if they need too. Even though I know most of what you showed here, I enjoyed watching this one as well. You content is very good and we're enjoying it very much!
Thanks so much, and I am glad you are enjoying the videos!
Don't you dare stop with the amazing videos. I wish we had teachers like you at school. Another excellent and very illustrative video session. THANK YOU! 👍
Wow, thank you! More videos coming soon.
Outstanding demonstration! Clear and concise.🙂👍👍
Thanks so much, glad it was helpful!
Really enjoy your channel. My father was a Naval Chief, his job was hull technician. At five years old he had me in a navy base wood shop he ran at night for the base. Today he would have been looked at as the ultimate maker. God rest his sole. I am about to make a 29.9 feet trawler to travel the loop or part of it. You should consider a new title. Professor! lol. Take care. He taught me all about wood and making with wood but left out the stuff about resin and sheet metal. Well, I learned sheet metal in the HVAC business for 20 years and later learned resin on my own. Thank you for the complete explanation format. I have an old picture of dad standing inside of a mold where he made PT 50 foot fiberglass hulls in Vietnam back in the 60's.
Wow, very interesting! Thanks so much for sharing! Sounds like a very interesting project you have planned. We see a lot of loopers come through the intra coastal waterway in our part of the Gulf coast. Looks like it would be a very enjoyable thing to do. Best of luck with your project, and thanks for watching!
I greatly appreciate all of this information. Thanks!
Glad it was helpful!thanks for watching!
Ceramic tile or glass makes a great sturdy mixing surface, this is easy to clean.
Great tip! Thanks for watching!
I've watched every single glass ing video you've ever made , and followed along the way of the 2900 , your technique and explanations have improved my own skill tremendously, and has taught me to slow down and take my time and it really shows in the final product, love this channel!
That's awesome, thanks so much for watching! Glad the videos are helping you with your projects!
I really appreciate your help, its a lot but we always have a video for reference later if we missed or forgot anything. Keep up the good work.
Thanks, glad to help!
Ild like to see a bass boat transom redo. I know you specifically do sea/inlet boats but maybe an older 80’s-90’s.
Also long hull scratches or wider flatter spot like 4-6 inches or more in size.
Thanks for the suggestion. I have a 2 part gelcoat repair video series here on the channel. You will have to scroll back a good bit to find it, but they are 2 of our most popular videos. It shows gelcoat repair on scratches simular to what you are describing. Hope they help
You are finding your sweet spot on these videos.
Glad you like them! Thanks for watching
Yep, agree fully
Another great video. You have a skill that needs to be shared and a hell of a teacher.keep them coming Capt.
Wow, thank you very much!
only My second or third vid I have seen of yours...excellently done sir.,,and exactly what I needed TY !!
Thanks for watching! Glad to help!
Thanks for sharing all this info. So much good stuff.
Glad it was helpful! Thank you for watching and commenting!
Another superb video, many thanks
Glad you enjoyed it, and thanks for watching!
Hello! Thanks for the shout-out 😀😀 And the info about filling the holes is, as you said, *exactly* what I need. You are most kind 👏👏
You are very welcome! Glad to help you out any way I can! We will be posting more vids related to the kind of work you are doing on Twiggy, so stay tuned.
A video on how to fix "spider web" looking cracks in the gelcoat would be great
Thanks for the suggestion!
Thanks learning a lot the long videos are great.
Glad you like them, and I appreciate you watching!
Capt Joe and fish bump family you make it look easy but when doing this material it really takes some where with all timing is everything and a BIG thumbs 👍 on more videos really appreciate your time !
Thanks 👍I appreciate you watching and commenting!
Thank so much for the “fluff free” discussion! After a weekend of you tube learning, I want to hear “just the facts.” Excellent delivery style, good camera work as well.
Glad you are enjoying the videos. Thanks
I started watching fiberglass and boat repair because my Sea Fox got a crack in the deck. I feel confident I would be able to do the repair but my wife is opting to hire a professional service. Thank you for your videos I found them to be very informative and interesting will be able to oversee and understand what gets done on our boat thank you
Glad the videos helped to understand the process of fiberglass and gelcoat repair. Nothing wrong with having the work done professionally. It it good to know when it is more than you may want take on. Thanks for watching and commenting!
Thanks so much for making these videos, you do a great job with this channel!
Glad you are enjoying the videos, and I really appreciate your comment!
Thank you for this, this is so helpful.
Glad to help! Thanks for watching!
Another great video capt Joe. thanks.
Glad you enjoyed it!
Another awesome video, very much appreciated 👍🇦🇺
Glad you enjoyed it!Thanks for watching from Australia 🇦🇺!
Dang man that was a Mouth-full(Spanky)line from Little Rascals.
You are making me warm up to Poly.
How can folks afford $300 a gallon for filler.
I am like I said before, Not a beginner and Not a Pro.
But You can make 53 minutes pass quickly and easily.
Dont ever feel like you need to short cut these Videos, These are packed with well valued content.
You MAY have missed a calling in Teaching.
I have made or left several comments on other videos.
But I can't convey how refreshing it is to watch quality installs by a Pro.
Haha! I used to watch those guys when I was a kid, good stuff man! Thanks for watching and commenting!
found the 3m premium on amazon for $197.
Great content! Look forward to meeting you!
Thanks so much, same here!
Great info you can rely on. Hi from California
Thanks so much, we appreciate you watching from California!
Good Info takes time to deliver so videos need to be sufficent length to impart this knowledge
Glad you think so! I appreciate the comment!
Wow this is fantastic information thank you so much
Glad it was helpful! Thanks for watching!
Good stuff well on your way to 300k subscribers
Thanks for the comment and encouragement, it is much appreciated!
My favorite tools for filler work tools are a waxed melamine board for mixing, a 4" dry wall knife, a drywall cheese grater for removing "b staged" excess, and cake icing spatulas for fillet shaping. If you have deep pockets Freeman Supply makes amazing fillet shaping tools. Great info as always!
Yes, all good suggestions! I actually have some tools from freeman, and some others that are very good. Maybe I will make another vid on fairing and shaping fillers in the future and use some of those tools! Thanks for watching
Screw hole through the deck repair answered, thank you.
Glad you got it figured out! Thanks for watching!
I'm going to be repairing cracks in my hull. I have watched a ton of videos. I have watched your videos and you are my choice of teacher's. I will be following your instructions for my repairs. Thank you so much for sharing your incredible knowledge and expertise. I hope I can do as well as you making it look great.
Thanks, and best of luck with your project!
love the videos! Idea for the future would love to see some gel coat (white or black) with a glitter over not all glitter just a dusting and then I believe it is clear over that. Just a repair section how to would be cool to see.
Thanks for the suggestion!
Great info once again.
Glad you enjoyed it!
Ty for the advice you gave me about my boat it’s all white and has a 6 inch blue ring around the top of it
You are welcome, glad to help!
Joe is making a library of boat repair videos, not just the fixes, but clear explanations of why.
I like the learning process on how to fix things the right way.
We are working on it! Glad you are enjoying the videos!
Great video 🦾🦾🦾😎
Thanks for watching!
Thank you for a good video on using fairing compounds. I am stumbling thru gelcoat repairs (mostly thremal and stress cracking) on my 22 year old Beneteau sailboat. Apparently thickened gelcoat is not the best way to go when you have "demeled" out the cracks and you are trying to fair them back to flush. I guess I messed that up. Good thing I am practicing on a small removeable hatch first. Not the whole boat. This work is very frustrating and a tougher learning curve than I thought. DIYers can do it but not without some trial and error. Don't expect perfect or professional results. I know I have been and will make lots of first timer mistakes. I am hoping to cut out a few of them and avoid making an unrecoverable mess by learing from professionals. I salute those who can do this well. It ain't easy.
Glad you are enjoying the videos! Yes, there is a learning curve for sure. It is always best to practice with some inexpensive or non essential parts first if possible. Remember perfect Is really difficult, sometimes good but done is better.
Your content is GREAT and much appreciated! This stuff can be so confusing and your videos offer clarity. So thank you!
Thanks, glad you are enjoying the videos!
Your videos are some of the best info out there on the subject. If you get some time could you do a video on applying, mixing, and repairing gel coat for spider cracks on the hull. Keep up the good work.
Thanks so much, that's a great suggestion. I will try to make that happen for you guys!
Excellent lesson for us to learn!!! Thanks for that video!!!
Thank you so much, I appreciate the comment!
Great stuff. I just found your channel and I’m glad I did!
Awesome, thank you! Welcome to the channel
Perfect keep the videos coming. Good teacher. Thank you captain.
Thanks, will do!
I truly enjoy the videos and getting tons of value information!
Please keep it coming
Thanks, will do! I appreciate the comment
I have been doing glass and body work for decades and I'm impressed. Really good stuff!
Very cool! Thanks for the comment, it's much appreciated!
Great video ,tips,discussion. Valuable information. Thanks! I’m doing extensive scratch damage repair from hurricane Sally. As well as thru hull work. This is helpful.
Glad it was helpful!
Thank you for providing these videos. Great service.
Glad you like them! Thank you for watching and commenting
Good job fair informative
Thanks,Glad it was helpful!
Hats off to Logan for keeping up with you Captain! Great video as always. Please don't worry about the length. You have great content and a lot of information to get out there. Please keep up the good work. When are you going to get behind the camera and let Logan show us how he does it?
I appreciate that! I will tell him you said so, but I think he likes being behind the camera pretty good.
I use ground garden lime as a filler or filleting with epoxy because it is so strong and light. The lime is also very cheap.
Very interesting, I have never heard ofdoingthat before. Thanks for your comment!
This would have to one of the best resin comparison videos out.
I've been using predominantly epoxy resin on a stitch and glue design. It's nice to see all the other resins in action with a comprehensive explanation of the pro's and cons based on merit and experience. Saves average Joe having to spend a lot of money doing these tests.
I have used a polyester flow coat purchased for a test because I couldn't find the right information I was looking for. I selected a neutral finish coat as I had an outdoor cabinet which I could use the remaining product on.
I liked the properties of polyester for bottom side finish coat, UV stable, high impact resistance. My build is just a little 12 foot punt and it will likely get beached on the sand, so I was on the search for something durable but still repairable.
My test was on the bond strength to epoxy. A highly contentious subject (poly over epoxy) So I did one sample with epoxy base prepared with scotch Brit only and the other with 40 grit. The 40 grit sample required two additional coats of epoxy to fill the weave suitably so that I could use the 40 grit without cutting the glass. In the end I concluded it could be done, although I was still hesitant because the Scotch Brit sample failed very easily, so it's heavily reliant on the mechanical bond. The key to success is certainly in the preparation and it's likely why people don't recommend it, as you can't control what people do when it comes to prep work.
I later found a vid from Andy from boat works today who explained this process very well.
I'm about to test the abrasion resistance of a two pack product in Jotun hardtop AX. This is the base white and blue for the remainder of the boat colour scheme. It would be cheaper to me for It's use everywhere on such a small build, it doesn't warrant multiple products, other than the Jotun pengaurd HB primer (predominantly used as a filler, not a primer). I have used and like these products, it has great serviceability as it has unlimited recoat time, making repairs easy. However I'm not sure it has the hardness for running up on the beach, but it's serviceable.
I guess where my curiosity leads now....is vinylester over epoxy suitable and is there vinylester gelcoats? My limited research says they are more compatible.
The recommendation from builders I'm working with, is antifouling (non shedding type) mixed with thinner to increase hardness. As it becomes much more easily repaired in comparison to two pack paints. No priming etc. We are talking trailer boats not necessarily requiring a true bottom paint/finish, such as gelcoat. Especially considering it's an epoxy build (sealed). There is one interesting piece of knowledge written in the Gougeon brothers blue book. They say that epoxy was designed when prepared correctly to be sprayed directly with modern two pack paints. I found this to be true have done my own tests, I actually found my pengaurd HB primer to be softer (obviously sandable) than the two pack finish! Bond strength was impeccable. However, there ain't many stitch and glue boats you can just paint straight up without a good bog, fair and high fill prime to get a reasonable finish. This was more applicable to your Brite finished boats with the odd pinstripe!
I guess I'm telling you this, not to solve my curiosity, but to see the thought process of someone who knows far less and see if there are any lessons in some of these thoughts for your material.
I think what we need to move away from a view in society of this is right or wrong. But rather frame it as you have as pro's and cons. I'm a big supporter of knowledge sharing. In that process the truth finds form.
Keep up the good work 👌
Wow, what a thoughtful comment, with lots of insights! I really appreciate you taking the time to share your experiences. I will be doing some tests with vinyl Ester and epoxy very soon, also some poly over epoxy to help answer some of the more frequently asked questions we are getting here on the channel. Thanks so much for watching!
Great stuff, Joe!! Everything you put out is absolutely great info. You’re doing an awesome job of making it understandable and applicable. I appreciate that
Wow, thanks so much! Glad you are enjoying the videos!
Thank You for the awesome information !! this is going to save me a lot of time come Spring when things thaw out here in Northern Pa. !!
Glad it was helpful! I appreciate you watching
Always super informative!! I've been to paid trade seminars and you're spoiling us with the ease of you tube -thank you- [A request ] could you do a strength and impact test on the different finishing materials over cured lay up... ie. putties ,smoothing coat of resin, gelcoat and whatever your method with a finished great looking exterior gelcoat or paint? My ultimate goal is to make a fiberglass body for a 72 Datsun 510 -in time after a lot of practicing on smaller projects, your teaching is great. thanks Bret
Thanks so much! I will try to get some more testing out for you guys. The Datsun project sounds like a cool one!
Awesome video!
I am going to making a custom fiberglass shower pan and cabinet in my camper and I feel confident after watching these videos!
Thank you, and best of luck with your project!
The content, tips and demonstrations are very confidence building. As a drywall mudder/taper/finisher and painter by trade, I appreciate the similar techniques but I am learning what actual materials to use for canoe & kayak repairs and restoration. I dream of shop like yours to get going on my own projects. Thank-you for your videos and expertise once again. EPO
Thank you very much for your comment! The skills you have from doing drywall and paint work should make you a natural at fiberglass and gelcoat! Glad you are finding the videos helpful, and best of luck with your projects!
Hello Capt. Joe, great videos! Can you provide some guidance on removing bottom paint and making repairs below waterline?
Yes, I will be helping my brother with his sailboat bottom paint soon. I will try to touch on the process you are looking for soon! Thanks for watching!
Great job Captain Joe. Keep the videos coming , great info , technique and presentation. I honestly can't believe how fast the time flies by watching and learning. Reinforcing what I already know and filling in gaps in my knowledge or showing me new techniques and tips..Thank you!
Thanks 👍 glad you are enjoying the videos!
Thank u so much for taking the time to explain all these things to us. Great content. And much love from Maryland❤❤❤. Im about to start my boat project once the weather breaks. I have to replace the flooring in my 1978 Wellcraft so your videos will def come in handy when i go to do so. I will keep u posted on that project considering i will be starting a youtube channel so we shall see lol. Just wanted to say thanks again
You are very welcome! Glad you are enjoying the videos. Wish you the best of luck with your Wellcraft!
Hi Joe , big subjects and one of my favorite issues as so much miss info on fillers and fairing compounds.
Despite the great job that West System has done showing how to make your own putties and filler using a ready made poly or epox product is usually way way better. If for no other reason than you get so much better consistency. The additives need time , up to 24 hrs to be fully wet out by the resin so mixing at the last minute just doesn’t give the best long term results. But as you know sometimes you just have to do what ever it takes.
Great video
Cheers Warren
Yes, all good points! Thanks for watching and commenting on the videos. I really appreciate it
Thanks for the video! I really appreciate the information and the care that you employ in explaining things very well, especially for the novice diy type. I just bought an old champion bass boat that needs some screw holes repaired so this video is timed perfectly for me. Thanks.
Glad to help, we just posted another video that you might find helpful. Thanks for watching!
I'm in the process of converting a 1973 SeaCamper from I/O to outboard driven. I'd like to see how a pro would plug the large I/O hole in the 2" thick transom.
Thanks for the suggestion!
Thank you for all your videos. I am learning a lot. Which filler is best to use on an aluminum stern drive?
Glad you are enjoying the videos! I would recommend epoxy for aluminum stern drive repair. Thanks for watching
Fish bump family just curious could you make some quick seat bases on a budget maybe some lids as well I think boats are great when you can buy , build and repair them and not sink tons of money and or go into major debt to enjoy them and still have money left over to enjoy with family and friends God bless Fish bump family Thanks for what you do!
Thanks for the suggestion, I will try to touch on that kind of project soon for you guys.
Eben here from South Africa, I absolutely love your videos and am a new subscriber. Your videos are clear and concise and there is always a huge lot to learn. Thank you for putting this together. I have by accident ended up using a tomato sauce or mustard sauce squeeze bottle for my acetone, it has the little cap for the spout and seals good enough to not evaporate and they come in different sizes.
Wow, thank you and welcome to the channel! I think you might be the first comment we have gotten from South Africa, it is much appreciated!
Hi captain. Thanks for helping me so much with diy on my boat. I have watched other Chanel’s and found them to technical which put me off trying.
So thanks again.
I do have a question for you I would like to bring my hull back to the original gel coat. But there is multi coats of anti foul. Do you have any tips as to removing the old anti foul.
I now thank god I have found your Chanel. Keep up the great work.
Wow, thanks for the kind words! Glad the channel has been helpful to you! I will try to touch on the bottom paint removal methods for you the next time I have an opportunity in a video. The basics though would be to carefully remove the old bottom paint with the correct paint remover or by carefully sanding it off with a vacuum assist sander or grinder. If the gelcoat underneath is in good condition, and is thick enough it can be wet sanded, buffed and polished back to a shine. If it is in poor condition, or to thin, you would have to add more coats of gelcoat, then wet sand, buff and polish it out. I hope this helps and I wish you the best with your future boat projects!
Fish bump family was also hoping for some pouring foam techniques and tricks that would make the process somewhat easier per say Thanks again from us DIYers
Great suggestion! I will work on that.
I've used pro strand.. a good product
I agree, thanks for watching!
Nice work thank you for the lessons. I really look forward to watching your videos. I have a Old Town canoe with bottom scratches i would like to fill and re-gel the canoe. should I prime first ?
Thanks, glad to help! We usually prime when working with wood or new Coosa.I would imagine if your canoe is fiberglass, and it is clean and dry you should be able to start with your filler, or your gelcoat. I hope this helps and best of luck with your project!
Thanks for all your videos...can I fiberglass around hardware cloth? Thanks
Glad you are enjoying the videos! I would imagine you could fiberglass over hardware cloth, but I can't think of a time when I have done that personally. I wish I had a definite answer for you, maybe you could experiment with it first beforehand. I hope this helps and thanks for watching!
Thanks!
Love the videos. What/how would you fill screw holes that you don't have access to the back? I had to remove rod holders under the gunnel in a skiff. If I put anything in the hole it will just fall into the hull.
Glad you are enjoying the videos! The 3m high strength filler is very good. I also like a product called formula 27. I hope this helps and thanks for watching!
Do you have any videos About Deck screws coming loose and filling them. And replacing screws back in.
I don't have a video exactly on that topic, but I would imagine you could you some of the info in the filler selection video to help you. I will try to make a video on this topic soon for you guys. Thanks for Watching!
I've seen oriented stranded board (osb) used to build boats. What is your thoughts and recommendations for sealing off the osb to be absolutely water tight bond ? CSM size and woven size ?
I have never used osb on any boat work. I would have to do some research on that on. I don't think I would personally use it vs marine plywood. I wish I had more for you on that one. Thanks for watching
Great stuff👍👍 after you glassed the plywood in previous videos,could you fair the fibreglass before gelcoat for a better finish 🤔
Yes you can. We are uploading a video on that process right now. It should be available for you to watch soon! Hope it helps and thanks for watching!
@@FishBumpTV Thanks Captain👍👍
I have repaired the fiberglass on the bottom of my boat (6" W x 12" L) and feather-edged the gel coat around the repair. Can I use tinted epoxy and colloidal silica to rebuild the gel coat, and if so, will that seal the fiberglass sufficiently, or do I need to come back with a gel-coat finish over the epoxy? Thanks in advance.
You’re videos have been incredibly informational, thank you for all you do! One question here - What resin would you recommend to waterproof plywood for floor decking that will have carpet on it? I initially planned on using polyester to ensure binders in the mat are being broken down, but if there’s no gel coat that’ll be over it, would epoxy be better for it’s water resistant qualities?
Glad you are enjoying the videos! Both resins can work, but there is a third option. Vinyl Ester resins block water like epoxy, but will work with csm. Hope this helps, and thanks for watching!
Thanks for all the tips. Do you have a technique to fill in nail holes but on a vertical surface? Just use a thicker filler?
Yes, a thicker filler will work better for vertical surfaces. Thanks for watching!
@@FishBumpTV got it. Thanks !!
what calalyst are you using with the 3m premium? i missed that sorry. can you get it in white? i'm doing very crude patch jobs on fiberglass below water areas that'll never be seen by the public. i'm not looking for pretty, just looking to seal it quick and efficiently.
It uses a paste type hardener that comes in tube with most polyester and vinyl ester fillers. Most cans come with a tube and it is usually blue. Although red and white hardener could also work. I hope this helps and thanks for watching!
Hi Joe did you use epoxy on your 29 or all polyester with gelcoat to cover
The 29 is all isophthalic polyester resin, 1708 and 1808 biaxial glass over gelcoat. Probably 95 percent or more of all fiberglass boats on the market are polyester. Epoxy is still a great material, and I plan on using it in some of our future projects. Thanks for watching!
Yikes didn't know about polyester filler not good below waterline. How about the West Systems batch you did with poly resin? I'm assuming it's the poly filler and not the resin that's the problem. Looking for good option to use for scars below my waterline to top with gel coat? I have 5 gal poly resin and 5 gal of Arjay 2011 Medium Weight polyester bonding compound still in stock from my transom replacement and glass work. The Arjay use MEKP and I like that when bonded together with wet glass same catalyst. But after seeing this I'll order up some 3M for the scar repairs. I see some top the Vinyl with a poly filler for final sanding on high visibility areas. Is that OK or is that poly filler bad also at risk as a top coat?
When I bonded my engine bracket to the transom (two days ago), I did three wet glass layers on the bracket side, a good wet troweled layer of Arjay 2001 POLYESTER bonding compound on the 36 grit sanded gelcoat transom outside (to fill any imperfect surfaces) all squished it as I bolted together with 12 stainless 1/2" through bolts. Is that a potential filler/water incompatibility area? Maybe I should 5200 instead of gelcoat the exposed edge? Boat lives on trailer and not water so I hope that's ok. Many many thanks, and BTW your pace and fire hose of information was PERFECTLY DELIVERED in tempo and content on this. Don't slow down and don't speed up (much)🤘
Usually polyester fillers are considered to be best used above the waterline. It is because over enough time submerged, water could migrate into or through the poly. Vinyl Ester and epoxy are best at stopping water. That is why epoxy barrier coats are so popular on polyester hulls for blister prevention. There are usually several ways any job or build could be done with success. I hope the info in the videos will help everyone do the best job possible based on there budget and amount of time they have. I hope this helps and best of luck with your project!
Question..can you use mekp for catalyzing Bondo etc or must it be the paste hardener?? Cheers
I believe you can, but it is not common practice. Maybe you should run some test batches first just to be sure. Thanks for watching!
What about marine Tex? Do u recommend it?
Yes, I have used it before with good success on certain jobs. I may do some more filler test in the future for you guys. Thanks for watching!
Great video. I'm working on an old ProLine and there are many holes drilled through the gel coat on a horizontal surface. What would you use to fill holes on the horizontal?
Thanks! There is no one filler that is best for every job. We will be making more videos on this subject soon, and maybe show some other option. All the materials we show in the video could potentially work one wY or the other.
I'm starting to rebuild a 1975 Reinell. I want to repair and "paint" the hull (exterior) a new color. It's obviously an old gel coat. Can I paint over gel coat? What prep work is required? What type of paint should I use. And, what are the pros and cons. Would love to hear you talk about this topic even if you don't make it a full video. Thanks. Mike.
Yes, you can paint over gelcoat. The surface would need to be thoroughly clean, then sand with 220 grit paper. I like a epoxy based primer like U.S paints Awlgrip 545. Awlgrip makes a very good marine paint system that we have used with good results. I will try to touch more on that subject for you guys soon. Hope this helps, and thanks for watching!
Thank you. I'll look for your additional comments on your video(s).
I have been watching your videos for a long time. I now have started my first big job. Replacing the deck on my 5m half cab. When i pulled up the floor i found 3 screws drilled from the bottom into the hull. Why was this done? I asked the local fibreglass shop and they said there is no reason to do it. What is the best way to fix this. I was told to knock the screws through and then tape the outside then use resin to fill and glass over on deck side only. Can i use any resin? I have epoxy to use on my deck and Protite low styrene resin
What do you think of adding styrene to the 3M vinylester premium to use it as a skim coat? I find that stuff sets up really fast compared to polyester.
I have thinned it with vinyl Ester resin, before. I have not personally thinned with styrene. You could do some test batches or I may try it and see. Thanks for watching
BUMP! Awaiting the, "How to color match off white gel coat using yellow tint pigments". Because I will need that in my bag. Golf term lol...
Haha,Yes Sir! Hope to get a gelcoat color match vid out for you guys very soon!
after my polyester resin dries hard, do i have to sand before applying each layer of CSM or Woven? i hope this isnt a dumb question. like, say i prime my part or piece of plywood with poly resin, if i let it dry would you suggest sanding before applying my CSM
Yes, you can lightly sand or scuff up the surface of the resin with 60 to 80 grit paper, but you don't want to sand through the primer coat of resin. You don't always had to wait till the resin primer coat has cured completely, as long as it has tacked off, you should be good to go for your next layers of glass. Best of luck with your project!
What kind of die did you use to color the resin? That was a really nice trick.
They sell it at most fiberglass distributors. You just have to ask for red catalyst dye. I hope this helps and thanks for watching!
@@FishBumpTV I was binge-watching your videos that day and it came up in other videos I watched later, but thank you for your answer and all your videos
Subscribed! I have a exposed fiberglass strip where i have constantly beached my jet boat. What product would you recommend? I figure i can maybe just paint a coat of resin or gelcoat over it to protect it. No more beaching it.
Thanks, and welcome to the channel! We used to repair a lot of rental jet skis that had the same problem. If there was a lot of wear into the actual fiberglass, we would always add some new fiberglass to build it back up. Then we would paint or gelcoat it. If it is just starting to wear through the gelcoat, then 2 or 3 coats of gelcoat would seal up the exposed glass fibers and make it look better. I hope this helps and thanks for watching!
I was wondering if I can use a poly or vinylester resin to "bring back" my 3m vinylester filler that arrived with the lid loose?
Yes, it should work. I use polyester with polyester, and vinyl ester for vinyl Ester fillers. I would do some test batches after thinning before using on your finished product just to be sure it cures properly. Hope this helps, thanks for watching!
@@FishBumpTV Thanks, I appreciate your help. And here lately I've learned to do test batches of EVERYTHING. I had a "fresh" gallon of poly resin that didn't kick and cost me a ton of sanding lol.
nice one sir, I truly appreciate it. I learned a lot. but I have one question, what if milled fiber only on polyester resin and no selica? would it still do the job? what does selica do? thanks, have a nice day.
The fibers add strength, the colloidal silica thickens it. The two seem to work well together. Hope this helps and thanks for watching!
I see, thanks.
Have you ever used expired 3M vinyl ester filler? I just tested a small batch which is about 6 months pass the best for date - it cured nicely. Will it stick? What are the risks?
Hey Mr Joe, is there an expensive diy hvlp spray gun that you would recommend for spraying small gel coat repairs? Also what would you recommend to use for a guide coat when repairing and sanding a black or dark blue gelcoat?
If you are looking for an inexpensive hvlp gun that can spray gelcoat we have one in the links below the description in our latest mold building video. Our local Lowes also carries one that is around 70 dollars that does a surprisingly good job. I hope this helps and thanks for watching!
@@FishBumpTV ok thanks I wasn’t sure if that gun was for spraying Pva or for gelcoat
Can you color grade filler if not using a gelcoat? I have a camo Gheenoe Classic, the interior is a tan-brown that has some holes I would like to fill.
You should be able to add some pigment to most fillers. I don't know how close you will be able to get though.I would try to start with a filler that have a tone in the general ballpark if possible. I would do some test batches first to be sure you get proper cure. Hope this helps and thanks for Watching!
After using 3M High Strength Marine filler, you can come right over the top with gel coat (below the water line)?
Yes, I will usually sand the filler some to give the surface some bite, then wipe with acetone, then gelcoat. Best of luck with your project!
I have some experience with glass... I like the gel-coat finish for its durability.....I want to refinish my concrete pool and as most concrete pools from the salt today it etiches the surface... My plan is a pressure wash on the surface and then spray a thing gel-coat for adhesion... At that point, I am only trying to smooth the finish and waterproof at the same time....I want to come back with a spray pool paint.... I am looking for adhesion, smoothing and waterproofing.... I think this method will allow me to be more aesthetic without very expensive glass tiles and the surface should be slicker and easier to clean....Your opinion
I will try again! There is a product called ATPRIME2 that might help you seal the Concrete.👍
I don't deal with swimming pool applications much, but I think a epoxy or vinyl Ester based product would be best for what you are trying to do. They are going to bond more aggressively and stop osmosis or water intrusion better than polyester based gelcoats, in my opinion. I have seen fiberglass pools with molded gelcoat finishes developed osmosis blisters over time and have to be repaired with specialized pool coatings. I am sure there are products made just for what you are doing, I don't know that gelcoat is the best material for what you are hoping to accomplish. I hope this helps, and best of luck with your project!
