Dang it ! I had questions, but by the end of the video you answered all of them lol ! I’m so glad I found your channel because I haven’t found another that’s so descriptive. The info you give like sanding grit , primer/paint properties, when and when not to do this or that etc. is unprecedented. Thanks for taking time to make these vids because there are lots of us who really benefit from it. I’m currently tearing down a 69 Roadrunner and have been so stressed about the body work part up until I found your channel. I’m totally confident now with all the info you’ve been giving. Thanks brother !
So very glad to hear!! We appreciate every one of these amazing comments. Thank you!!

Finally, a single place to learn many things at once. Thank you! Superb.
Thank you!!
I was nervous and scared as hell with all the products out there! Your video made it simple to understand. Thank you very much!
Glad I could help!
painting a car is pretty easy previding you have some gun skill I started at 14 been doing it ever since I'm now 64 just talk to your paint supplier their usually ex spray painters I've found them willing to help you out
Thanks , great information, very clear and direct , perfect!
Another very well explained video. Thank you for taking time to film, edit and post this video.
Glad it was helpful!
Thank you for sharing your wisdom with a lot of us,I’ve learned so much in a few days God bless
Thank you!
Once again , fantastic useable information. Many thanks.
Thank you very much
Thank you very much. This is the best explanation of how each primer is used that I have found to date. I now understand what is going on with the 3 primers and why certain things need to be done to achieve proper adhesion. Because of this, I have subscribed to your channel. Thanks again.
Thank you very much!
You are my hero. Finally found someone that actually explains.
Thank you. I try to make it clear and concise
Another great video for the novice hotrodder ...... answered a lot of my questions with reliable information .... really like your content ....

Thank you I tried to keep it simple.
He articulates everything your mind could possibly want to know regarding this subject. Fantastic- all info on big subject in one place. AWESOME WORK - thank you from New Zealand 🇳🇿
Great educational video! 20 yrs ago when I was a paint prepper, shop I worked in mainly used all Sherwin-Williams products including urethane primers. This was so long ago it was before water-based base coats. We used a light spray etch on all bare metals, and they preferred the body men to use filler directly on bare metal. Definitely a lot of products and procedures have changed since then. This channel has a lot of good helpful videos 👍
Thank you 👌🏻👍🏻
This guy is an excellent teacher.
Thank you so much
Excellent job explaining it sir.
Thank you!
Hey man im sending love - just a few hours before i watched this video i had ordered my primer- and watching your video im gonna sleep better knowing i finally got it figured out ( i was sweating thinking you were going say dont ever use this product) keep making videos peace

You sir an an encyclopedia of information... the best for us DIYers.... my summer project is attacking rust on my 2009 corrolla, and keeping the thing going for another 5 years
Glad we could help!
First time spraying vp 2050 today. Wow! This stuff sprays beautifully. 1.8 tip and it goes on like butter. Love the idea of using this all the way through the job.
Awesome I agree one stop shop 👍🏻
Thanks for a great video, this clears up a few questions for and old school 1 K paint guy. 🙂
Glad you enjoyed it

Excellent videos, clearly you know your stuff. Would love to see a video dealing with working a fiberglass body, start to stop.
I’ve actually had a couple requests from this. We will have to do one in the future
i use the strip discs, they are awesome,
Dam Travis pass me the test sheet after watching your vids I’m ready for it!!! All joking aside your explanation is so understandable it’s scary. It’s like no other I’ve been watching. My save folder is slowly getting deleted and replaced with your vids. Much appreciated for you sharing your knowledge
Hahahahahahahahahahaha thank you!!
Nice video. When I try to explain to people what epoxy I refer to it as sprayable glue that is water and (depending on the product), chemical resistant
Nailed it 💯💯💯
very informative thank you
Thank you!
I'm using a high build as both primer and sealer works for me nothing worse than shrink back, great video I was bored finger I watch it good info
Which primer?
Awesome!! Thank you

Thank you so much
As a dealer tech, you can't afford mistakes, but as a one income family 40+ years ago, you bought used cars, fixed them and became transportation for everything. Even then, I would sand to bare metal for repair & a color change sometimes. I was shocked to sand a rock chip and find the "fingers of rust" spiderweb out 6", 8" or more. This scared me! We was going on under the paint to allow that? Not knowing it was fixed before using a standard primer, a standard filler, a standard sealer regardless of paint, single stage or base coat / clear. As chemistry has changed so much in 4 decades, now retired with time to research products, almost became more confusing to me. Only to find your channel and get explanations and straight answers from someone other than a guy behind the counter.
We get flash rust and serious rust in the upper Midwest states over winter as rock chips are not cleaned, treated and ignored. It is maintenance. No different the gear oil in the final drive. It gets attention once loud, obnoxious and headed for disaster. Then, it may get its first gear lube since new, but has 148 miles on it. Travis, thanks again for a great bucket load of information. Epoxy for my vehicle! Marketing drive the product and "DTM" is showing up everywhere and it scares me. It is not needed if you remove the old finish, sand and clean, spray. It implies that an acid, weak, strong, phosphoric or other is required. DTM to me, logically says skipping a step and costing more. I don't have a "Vibrance VB2050" budget, but I do have time. Not like a 34 year old guy, but one who will do each step, wait for it to shrink, do something else and revisit those panels later. Am I wrong? DK, Omaha. Great info.
Hi Dean! Another epic novel! 😁 Just kidding. Yeah, I hear you on the elements in the midwest. It's a killer. They don't call it the rust belt for nothing. One difference also is the difference in metals that are used from 40+ years ago to today. Some vehicles years ago you could find galvanized metal in certain areas (Mustang rockers) and usually held up pretty well. Now, all the sheet metal has zinc coatings so you dont see that spider rust as much as you used to.Then there is HHS, UHSS, alloys with boron,laminated steel,aluminum and so on. So you really need to know where and what it is. High tech stuff. Take care.
You are 100% correct there’s so many ways in this industry that you can slice anyone project but you were on the right path. We’re happy to help and thanks for watching.
@@SYLVESTERSCUSTOMS Helping others succeed in their project using best practices is what we do. You teach, I learn, pay it forward. That is a true blessing to allow a total stranger to do it and be happy. Time is short.
Travis, you pick some great topics for your videos, nice!
I will say those that use product and let it cure, then destroy sample A, B, C etc get huge hits and likes. It is like project farms, except for automotive body.
Did you ever see MrFireman164 do his Ospho to body filler torture test. I haven't checked but 1.4M views and thousands & thousands of likes & comments. Stay healthy Travis! I hate sinus issues, plus the sales / tech for my electrodes & controller, they gave up and quit. Bummer! DK, Omaha
Man I've been painting, stripping, restorating, and rebuilding for 44 years. If you would write the Painters-Filler bible I would buy it no matter the cost. I found out about flash times decades ago on my 71 Chevy truck. Painting the rebuilt control arms. I past the flash time with the second coat and it crackled. I spent twice the time removing all the paint then I spent on cleaning, priming and painting the parts. I wasn't too stupid then but now I realize now just how much I didn't know then. Thank you for a educational video.
Hey! Thank you very much 🙌🏻
Thank you!!
🙌🏻🙌🏻
Great video. I use VP2050 all day and love it. Definitely a slow sanding product, but it’s physically tough as nails and I trust it with my life. I also use Tamcos 53XX series, best high build urethane in the business, period. I also love Tamcos 770 series, another hi build epoxy.
Thank you.
Polyester for high build. Just need to seal them or they might fail. Also need a 2.0 tip gun to spray it correctly.
ever use 53xx over etch? Can you?
Id like to make a few comments on the Polyester primer. First off l would never suggest spraying polyester over epoxy wet on wet. Because Polyester cures so quickly and so hard, it wont give the epoxy enough time to set up on the substrate, and often leads to delimitation in the future; lve actually had this happen to me. Epoxy should sit for a minimum of 72 hours, preferably baked several times, and then fully scuffed with 150-180 before applying polyester. Secondly in reference to the shrinkage (l was in the pool!) Polyester really doesn’t have any. Perhaps it just comes down to product difference, l used to use slick sand now l use House of Kolor polyester. Because Polyester, or at least the HoK that l use, isn’t reduced and doesn’t have a lot of solvents, the shrinkage is essentially 0 and what you see is what you get when you spray it. Those are just my opinions from experience but ld like to hear what others thing as well
Well said. I've tried a few polyesters. Some Evercoat and PPG VP2100. By comparison, I liked the 2100. PPG was having trouble getting some ingredients a while back so it was offline. That's when I found the 2050 and stuck with it. I have used DP90LV reduced as a sealer for bare metal before polyester and had no issues with decent flash time and using just enough epoxy to cover. I was told by an Evercoat rep that the new generation of their polyesters are direct to metal if using the correct catalyst. Wouldn't recommend the Optex poly. It's a gimmick. Good concept but not enough contrast to call a guide coat. Sands like concrete. "I was in the pool". I caught that! "Like a frightened turtle". 😆
Thanks chris!
In regards to shrinkage all materials have a certain level of shrinkage the footage that was shown does not show it as good as I could. However, there is a good amount of shrinkage that happens with the ever coat that we sprayed in this video however, the VP 2050 has very little shrinkage and because it’s not just a straight epoxy it is a highbuild, it actually cures in three days And is not continuing to lose weight when measured on a scale. With that being said, you can topcoat the primer that we used with a poly, but I agree with your comment if you are using a traditional epoxy. thank you for your comment.
@@SYLVESTERSCUSTOMS If either of your ever want to use a good polyester, l highly recommend the House of Kolor. Mixes with a hardener, no reducer, and sprays unbelievably smooth for a polyester. Like l said l used to use the evercoat slick sand and l had to reduce that by about 10-15% because it sprayed so chunky. This HoK poly sprays and sands even smoother than a reduced Evercoat product
@@looper451
Thanks for the tip. I'll keep that in mind if I have any supply issues with the 2050 again. Do you happen to have a ballpark price on that?
You confirmed exactly what I thought about body filler and polyester primer. Thanks
Awesome!!
I’ve used I think every kind of primer you can think of in the last 30 years. My hands down favorite today is valspar DTM. Fills good, sands good, good price, DTM, and can be used as a sealer.
Whatever works for you 👍🏻
love your content!
Glad you enjoy it!
Really like your videos I'm working on a 68 corvette would love to see some videos on working fiberglass thanks for knowledge 👍
I’ll keep that in mind. If you have instagram we just did a bunch on a cobra
Not having much luck with Instagram lol to old to figure it out. Do have a question I've been researching primers what would you recommend for fiberglass? Father fil g2 or vp 2050 or both? Thanks again for your knowledge!! If your ever in north Carolina holler at me
Good video
Thank you!
This guy knows what he talking bout 👍🏽👍🏽👍🏽
Thank you
🤣
like this guy....good info
Glad you enjoyed it
Working in a shop where we do a lot of overall paint on older vehicles, sometimes will strip bad paint to bare metal & using an etch primer to seal the metal will just use a sealer over the etch primer & then just repaint the entire vehicle, this usually works very good & have never had any problems
Whatever works 👍🏻
I guess if you’re a lot of restoration work & applying body filler, I can see how these primers would be beneficial too!!
thanks good info
Thank you
I am a 40 plus year painter, collision and custom work.
Collision work I worked on straight commision.
Would always turn in 80 -100 hrs a week.
I got paid 45% of the shop rate times how many hrs. turned in.
For example, did 100 hrs of work x 45% of $65 per hour.
45% of $65 = $29.25, $29.25 x 100 hrs.
$2925.00 per week.
This was in 2010 when I retired.
I would always 100% of the time use the proper sealer.
ZERO problems, EVER!!!
When I first started painting I did EVERY MISTAKE
there was, and then some.
BUT I LEARNED.
The last ten years I could do many cars with zero errors.
That was from learning and paying atterntion!
Redos and comebacks were ALWAYS FREE!
Eliminate those and you are making good money!
You had the BEST advise and how to for all the substrate finishes!!!
Most of my products were PPG.
Made a lot of money with PPG!!!
All the custom work was with House OF KOLOR'
Kosmoski started here in Minneapolis, Mn.
Easy products to get!
They used to be cheaper than regular colors, but notany more....
Thank you!!
What a wealth of usable information. I’m going through your videos now. I have questions for my own project. Working on a 41 Ford coupe for my wife and I just had the engine rebuilt. I’m wanting to paint it with an acrylic enamel, which I already have. I want the aluminum heads, block and oil pan to be painted same color. Questions:
1. Would you clean and acid wash, please keep in mind the engine is assembled and I can’t get water or other stuff in it.
2. Would you use epoxy or urethane primer? I want to do wet on wet.
Thank you for all your knowledge sharing.
I will not acid wash. I clean thoroughly with a degreaser scuff it up as best as I can use an epoxy primer and after that flash’s off go to paint. 👍🏻
This is BY FAR! HANDS DOWN! one of THEE BEST PRIMER TUTORIALS ON CZcams!
VERY DETAILED, VERY INFORMATIVE!
question though, once your body filler is all Worked out and you have sprayed a high build feather fill polyester primer, blocked that and primer sealed it...
What is best primer to be allowed over the top of the sealer if you STILL have some imperfections? Use a putty/polyester feather fill to get any scratches/imperfections out? Or just go over it with a few coats of a Polyurethane Primer block and Seal prime again? (And yes I understand that you said to only apply filler/putty polyesters over Urethane or epoxy and NOT on Direct metal, so I get that, but if having to re-apply a high build primer or putty for filling/fixing Imperfections, can i just apply some more primer sealer to just those putty areas? Or should I first apply some Urethane Primer over the putty/ployester areas, resand then seal?)
Or would it be better to just go with the VP2050 Epoxy Primer over my Primer Sealer since it is technically a Sealer itself, block that, then finish with a Polyurethane Primer and Primer sealer (Sealer layer used once again, 2wice now)?
Fir last thing to do before laying down my base coat? As obviously a primer sealer should be the last and final layer before base coat
Thank you very much. If your body work is where you need it to be if you are using a polyester primer, you would keep applying polyester until your body work is done and then you would be sealing it up. You do not want to go back-and-forth with different kinds of primer. It might be OK but you’re just asking for problems. This is specifically why I only use VP 2050 I can use it when I start and when I am finished and when that is wet sanded with 600 grit. Then I can go over the car with a sealer and basecoat back to back wet on wet.
Also, make sure you read the TDS sheet VP 2050 is not used as a sealer. You cannot paint over it directly wet on wet.
@@SYLVESTERSCUSTOMS that makes sense to me... However though after having to re-apply more polyester primer (like the Evercoat featherfill or Clausen All-U-Need) wouldn't i want to go over that with Urethane Primer, do 1 last FINAL block, then use the primer Sealer? Or should these Polyester Featherfill/high build Primers be only applied OVER scratches instead of any Urethane Primers? It just seems that these Poly-Urethane Primers have alot less shrinkage then the Polyester products so I thought that maybe a high build Polyurethane would just play it safer then the High Build polyester feather fill stuff...
I guess it would be also better on which decision at this step of the process to make, based on which of the 2 types of primers are easier and quicker to sand...
Again I REALLY have thought long about your advice to only either Etch Prime, then Urethane Prime... or if using EPOXY PRIMER, apply EPOXY PRIMER, then apply POLYURETHANE Primer BEFORE DOING BODY WORK (FILLER, PUTTY, POLYESTER FEATHER FILL PRIMERS) SO THAT ANY OF THE POLYESTER BASED PRODUCTS ARE NOT ON BARE METAL (UNLESS THEY ARE SPECIFIED TO BE DTM)...
So I guess what my question is, is that if I still had some small metal spots come through that weren't really high spots but lets say a high body line crease on a hood or top of a door panel, is it perfectly fine to go over that with some more DTM ONLY rated POLYESTER Primer? Or will I have to use the Self Etching Primer over these small bare metal areas???
And what about a PolyUrethane rated DTM Primer? Are those available? And if so Could I even use that still on top of body work before Primer Sealing? Or should that be Only applied on bare metal?
But I i do get that if I were to use a DTM Polyurethane over the small metal areas poking through, then NOT to go back and use a Polyester Featherfill DTM Primer again... As this seems the multiple layers of Polyester products would get wavy waves from shrinkage on the multiple layers...
I think answering this last FINAL Question will solve my dilemmas im having with the DTM rated stuff, When in doubt I would say that look on the Data Sheet to see if any of these DTM and DTM Polyester products have either typical shrinkage, very minimal, or virtually none!
I feel Like we are not only learning bodywork skills, but a blend of that and mad scientist chemists 😆 since if you study and learn your chemical compounds, it should REALLY Help out on what, with, when, where to use in conjunction or next to another chemical compound make up of another product... Whether its the same brand or another Brand...
I only use epoxy/acrylic hybrids or HOK A and B. DTM for the win...usually good for fiberglass too. What I dont like about hybrids is the claim that it is used as a sealer too at a higher reduction. I prefer urethane sealers as they are more UV resistant than epoxies/hybrids. I also use paint stripper to remove old coatings. I prefer to sweep up the gunk rather than have dust all over my entire shop.
Spray On!
I agree
What do you recommend for a stripper?
I've been using the VP 2015 for my 57 Chevy truck and it's amazing thank you for the video my only question is when you burn through do you go back with VP 2050 and touch that spot up or do you just use a urethane over the Bondo that you burned through
I always make sure I go back over it with 2050 before I go to a urethane sealer you need uniform coverage and if you just rely on the urethane over the areas that burned through it will shrink back and have a halo later on down the road guaranteed ask me how I know 🤣
Great videos! Thank you for doing these videos. What do you do for the backside of panels for protection? Remove e-coat and epoxy prime and sealer?
They all vary. We strip ecoat and epoxy. After epoxy some get painted some get undercoated and some get lizard skin
Thank you for response!
Really informative videos. Started out watching the ones from several different people but now just mainly watch yours. I'm restoring a 56 Belair and a nova ss at the moment, have 90% of my metal work done and it's time to start removing the heavy surface before priming. Just wondering if you or any of your followers have tried Picklex 20 rust converter, if it is worth the asking price. Don't have information on application as of yet but it is supposed to be compatible with the ppg 2050.
I’ve never heard of it we use rust mort converter.
Great info! I am a newby, working on a 54 chevy car. My local paint shop recommended me using Roberlo DTM 4:2 Urethane primer. I like what you said about the VP2050 for the hardness. I guess using the Urethane primer was not a mistake but could the VP 2050 be used as a sealer on top of it? Thanks for such a wonderful explanation!
I do not recommend 2050 as a sealer. Get an actual sealer.
Great video! Also perfect timing.
I am stripping my panels to bare metal. And once I was done, I am spraying Eastwood epoxy primer. I also have to do body work on it. So some thin set bondo. At this point would you spray 2k primer, sand, then spray sealer . Then base coat clear coat?
Thanks
We only use one primer vp2050 but yes you definitely could do it that way. I try and limit how many different primers I use because of potential failures etc. consistency is always best but do whatever works within your project and budget
GREAT Video! Thanks for Sharing! Proud to be a Subscriber! Have A Super Week!…..Gus
Thank you! You too!
Polyester primers basically have no shrinkage because there is no reducer to it, only MEKP liquid hardener. Urethane primers usually have shrinkage because of the liquid hardener and reducer added to spray it. 30 years of doing high end paint jobs and only use epoxy ( 48+) hrs dry time and polyester primer all the way to finished sanded in 4-600 grit. Use the epoxy in the end as a sealer and that combination of those two products has produced many killer jobs. The only flaw about polyester primer is that it offers zero flexibility and chips
extremely easy on door/hood edges..etc. so you need to be careful how much is applied in certain areas. Your video is definitely better than most that i have viewed on here.
I agree partially the only thing I disagree with is the shrinkage. If you do a shrink test on a bare panel you will see that all of the products have a level of shrinkage. Some are more than others weigh a 1‘ x 1‘ panel on a scale after spraying it with polyester only and then give it a few days and weigh it again then wait a few weeks and weigh it again. He will notice by doing this test the amount of shrinkage that no matter what every product has if it’s losing weight, it is shrinking if it stops losing weight, it is done shrinking.
@@SYLVESTERSCUSTOMS Never thought of looking at the weight aspect of it? If you sand it open and it still has a strong smell then the solvent is still in there. I guess the key here is that the type of work that we do
on these old cars there should be no hurry to rush the products. I find that most people that have issues when painting is because they are in a hurry and don't let things dry properly. I give the products plenty of time
to gas out. People also will sand and polish a vehicle way too soon because it seems to polish easier, well that is because it is still soft and then it dies back and you have to do it all over again. Be patient people. I have done the shrink test with clear before by leaving around an inch of leftover clear in the bottom of the plastic mixing cup and setting it aside for a few weeks, then look to see how much the puck has shrunk away from the sides. Pretty amazing actually and this test can be applied to primer also. Thanks for responding back and keep up the good work.
Again another informative video, keep up the good work. Learning something everytime I watch one. Do have a question though, the acid wash you use isn't available here locally, sure it is in some of the larger towns around or ordering it online but I was interested in some of the products I can get right here. What is your opinion on using SEM Rust Mort as my acid wash then Ospho on top of that before applying my epoxy before doing my body work? And also will 1k epoxy work to encapsulate the sheet metal and give me a longer window to finish my body work?
I recommend sealing the car in epoxy then doing your body work. Don’t use rust mort as an acid wash
Thanks!
Thank you!!
Wow this video was so helpful! I am in the process of shaving my engine bay. After watching this is seems like the VP2050 epoxy primer is the way to go... I am however worried about all the little nooks and crannies in an engine bay since I won't be able to DA sand a lot of those with 80 grit. I could definitely just use my hands and some 80 grit sandpaper in those spots but not sure if the pattern created by the DA sander is required for the epoxy to stick?
No we hand sand all of our cars before body filler
What do you recommend to remove thick bondo? Thanks, love the content.
Stripper discs or acid dipping is ideal
Thanks ! 👊🏻✌🏻
You bet!
Thanks for your great tutorial I have a question I bought a Dr Color chip I've toughed up my tailgate a quarter PAnel but I accidentally spilled my sealant /blending solution would you k ow a substitute or how to make on before my paint drys thanks again a keep up the great tutorial s
Unfortunately I’m not familiar with that
Thank you for the awesome videos a question that I have is how straight do I have to get my metal before putting on the filler or 2K primer. I guess my question is when the car sits out in the sun and everything heats up will the waves show up? I have my 67 Camaro door sheet metal all hammer and dollied out two within a 32nd and no oil canning present. I would appreciate your input. Thanks again for your awesome video series.
A 32nd and firm I say run it 👌🏻👌🏻👌🏻 I’d say 1/16 is where I like to be at minimum
heres one for you, 84 Fiero weathered ive had to do lots of sanding to get the roughness out of the hood and roof .which is SMC, the fenders and bumpers i think are the same urethane now there is spidering on the fenders and bumpers should I use epoxy after sanding down past the paint and maybe use a polyester primer to build over the spidering?? not sure what to do here as everything is flexible . urethane primer?? for the whole car? . Thanks in advance . great videos
Thank you! Yep strip it down all the way and epoxy. You are on the right path. If it was me, I would use VP 2050 to do the whole thing start to finish and not use any other primer. I’m not just saying that for no reason that’s all we use and we have great results.
Very informative! Although i did have one question. While doing an engine bay and sanding down to bare metal on some spots due to surface rust while other spots are only scuffed. Which primers should i use?
Because i was going to apply an etch to the bare metal spots only and a normal 2k primer over the whole thing. Or should i take a different route?
Best route is an epoxy highbuild hands down. Vp2050 is what I’d recommend.
Do you recommend taking off the replacement part primer to bar metal and what grit metal scratch (180 - 150) then epoxy primer
Yes I strip everything to bare metal with 80 grit on a DA then epoxy
I used to use Urethane high build primer to do my final sandblocking. I heard it takes much longer than polyester to fully cure and can produce urethane wave down the line. I loved how great it sanded. I have since moved to polyester (evercoat slicksand) but noticed its much harder to sand and the prices of Polyester primer seem to have skyrocketed. Thinking of going back to Urethane for final blocking. Is it true that it takes weeks to months to final cure and no more shrinking?
Depends on the product and mill thickness etc but yes it could. I use an epoxy highbuild
After the epoxy and bodywork then is it ok to use the polyester primer over the bodywork being you have the epoxy to keep moisture out? I've got a Cadillac like the one I saw in the back ground and it's going to be a work in progress. So I just want to make sure I do what little bodywork done without messing things up . Thank you for the videos they are very informative for use old guys trying to relive our youth in cars
Yes, exactly!! Thanks for watching!
Awesome video. I have a question hopefully you have time to answer. I had powder coated a motorcycle gas tank and fender. The coating shop did not leave a good finish look. My plan is to sand the powder coat to a smooth finish and then paint with 2k. I will not be using filler or build compounds. Not a show room peice.
Can I use a urethane sealer over the powder once sanded, I plan on having an edge on a weld that may go through to metal.
Or should I sand and apply epoxy primer and skip the sealer.
Thank you
Yeah sand the powder really good it’s strong stuff and you can go over it 👌🏻
I still like my DP 90 over bare metal first, but after my bodyfiller I'm going to try Evercoat super build over it. Have always used NCP 271 for my final prime, but at over 800.00 a gallon I'll use the 2050 reduced.
The main reason I like vp2050 so much is that it’s one product instead of having to use several. Which results in better consistency and less failures. But whatever works👍🏻
@@SYLVESTERSCUSTOMS I don't so much about failure, if I'm using the same products from primer, base coat to clear.
Best teacher on the internet!! Thank you sir!! I’ve been using HOK KD3000 for my project currently. How do you feel it compares to VP 5050? Have you ever used it?
Thank you! Unfortunately I haven’t used it. Which one of the three categories is it?
@@SYLVESTERSCUSTOMS falls under the DTM epoxy hybrid. Can be a high build first then reduced to a surfacer, then sealer depending on the mix ratio. Thanks for your reply. Was just curious if you’d used it before. I’m trying to keep to 1 product line (house of kolor) or else I would have used vp2050. Your videos have helped me tremendously during my process. Thanks again!
@@chetstevens4929 that’s great best route to go. Thanks for watching we’re glad to hear the successes
Hey sylvertercustoms I have a quick question , what body filler do you recommend ? I seen you use upol lightweight and ever coat rage ultra . I’m currently in school and working on my project but can’t decide what body filler to purchase . Your opinion will save me a headache .
Upol went down hill we don’t use it anymore. We use rage ultra or 3m platinum plus
So if I use the VP2050 and get everything blocked out to the point I'm close to paint do I seal it with the urythane and do a wet sand then base and clear?? Thank you for the awesome videos, I'm learning a ton!! Cheers!
You do not have to seal with a urethane and then wet sand. I actually block everything out to 220 grit, and then I wet sand with 600 and a spray urethane sealer and go directly into basecoat clearcoat after it flashes off. Here’s the caveat, depending on how good you spray you might have orange peel that Will make your basecoat and clearcoat look not as good so if you want to take the extra steps to wet sand, the urethane then by all means do so there’s a bunch of different ways you can slice this.
cre is the off brand of 2050- ? can you put these over paint ? thank you for your awesome videos you are very through at explaining things !
Thank you. CRE is the industrial version of the same product VP 2050 you are correct when they had shortages with the resin‘s. We were using CRE and it worked amazing. and yes, if you are going over an existing paint job, you can do that with his primary as well.
Slicksand (polyester) seems like it's not porous at all, used it to seal up a composite thermostat I'm experimenting with - I know its not the intended use - but it's sealed up a few leaks of coolant at 90c for a few months now. It's not the polyester itself that is porous but the additives mixed into the resin so depends on product, after all, every fibreglass hull uses polyester resin. Cheers for the video.
Thank you. Yeah they all have a different make up of chemicals. This video was intended for people to just help them get a clear direction on where they need to start so it’s not overwhelming. Thanks for your comment.
if you have the opportunity, put the car or pieces out in the sun, the suns uv rays are the best to make sure your primers are dry and won`t shrink later on
Try Southern Poly Epoxy... SPI makes a killer product.
Ok, so if I understand correctly. I start with bare metal, use wax and grease remover, then spray epoxy high-build sealer that can be sanded (the one you use). After it has dried for a week or so, the bodywork is then performed on top of that. My question is, during bodywork as I sand, if I start to see that I'm sanding through the sealer coat (like seeing pencil marks from a low area) I should stop and apply more coats of high-build sealer and let it cure for another week before continuing sanding/bodywork? Then, after all bodywork is complete, spray one last coat of sealer before the basecoat color goes down?
You are pretty spot on. You don’t have to reapply epoxy vp2050 until filler work is done. But if you are not happy after that you can re spot filler and 2050 as needed. Vp2050 is not a sealer. Actual sealer is different. You do that last before paint. We use Ecs sealer
So I use vp2050 as my first coat, and then do my body filler and any sanding/blocking. Assuming I don’t expose any metal, I can go right to a urethane sealer and then base coat? If some metal comes up during the blocking phase, should i do vp2050 THEN urethane sealer? Or am I ok to paint right on top of vp2050?
I recommend a sealer always. But yes seal up the metal with vp2050
Question: is media blasting sufficient prep for adhesion before applying epoxy? If my car body is completely media blasted do I still need to prep it with 80 grit for proper epoxy adhesion?
If the media you are using leaves a rough profile, then you are good to go directly to epoxy
Hey Sylvester. Can you put body filler on top of clausens all u need primer??
Yes you can. Just be sure to scuff it up
Great video so my question is there's no need to use self etch primer when you can use 2k for a sealer it that correct. !! Thanks
You are talking two different questions. Etch is for bare metal if you are not using epoxy or a DTM. A sealer is done before paint. Does that answer it?
I've been blocking the vp 2050 this weekend. Everything is straight now and looking great. But I have a couple of very small break throughs to bare metal. I'm currently at the 150 grit point. What would you do know? Just reprime again and go lighter on the blocking stage?
Correct depending on how much metal is showing you might even get away with spot priming
@@SYLVESTERSCUSTOMS Thanks! I really like the vp 2050. I expected it to be extremely tough to sand, but once I break the top surface it sands really nicely. Also if I were to use a sealer before paint what would you recommend? If anything. Cheers John 🍻
During renovation would it be appropriate for epoxy, then filler or body work then urethane primer or sealer, then base, then clear? Thank you.
That’s the standard yes.
When I get a new fender, aftermarket or whatever, I want to put a coat of something on the inside to rust prevent it from rust. Would you recommend Epoxy Primer for this or is there something better to use ? I've already used spray can undercoating, you know the black tar type stuff, but what do most people use for rust protection besides like Woolwax or that. I can maybe do some of that later, but I don't want to contaminate the outside that I have to paint yet. What do you use ?
We epoxy the bare metal and use a raptor liner over the epoxy
Never heard of raptor liner, is it a type of paint that comes in a qt can or something ?

I was banging my head watching primer tutorial videos just looking for the information you provide. Great video and explanations. If possible, could you confirm my reasoning on using the DP2050 primer: I’m taken off the clear coat on my 72 c10, but also had to go to bare metal on some areas. I do want to be able to sand after I apply this mainly because I’m learning and don’t expect to get this good right away. On the other hand, I don’t exactly know my time frame and want to use a product that could potentially sit for a bit before paint (project truck). Does this sound like the right product?
Absolutely. Vp2050 is honestly hood it all situations.
@@SYLVESTERSCUSTOMS can I ask your take on CRE epoxy primer? Only reason I ask is they offer a black primer and I saw another person saying when they don’t use DP2050, they will use this.
