Man, this dude deserves way more subs than he has. Does so much for his subs and really takes the time to explain everything
Thanks Alex, I have alot of people say that, all I can do is hope words travels & the video get shared. My #1 goal is factual information & to help others. I really appreciate the kind words & thanks for watching!
@@Darkwingdad thanks to you too for all the info! It's a great help! One of my fav channelS!
Wish I could like this twice. The scoring method as intensive. The level of depth in the explanation was deep. The methodical way that you displayed your examples before during and after sanding was just 🤌🤌🤌 I actually learned something about sanding today! Thank you for your time DWD!
I am so glad to hear this! Even if my videos help just 1 person to understand something & benefit it’s worth it. I know this video was long but I didn’t want to skim through & make it short, that defeats the whole purpose. I really appreciate the feedback!
dude I love that you're doing everything like 99.9% of us. Working outside on available surfaces. We cant all afford purpose built studios
I do use paint tents, but for tests like these it’s not necessary, if I know it has to be sanded I’m not too ocd until the end lol
These filler comparison videos have been extremely helpful. Thank you!
Anytime my friend, thanks!
Thanks for running through the tests and saving us the time & money
Thanks for watching! Ultimately it’s preference, but I will tell you I ripped my hair out with rustoleum, and majority of problems I see are people who use rustoleum. Those that have success waste so much time with drying/curing. Solvent based fillers are the way to go!
Money! Thanks for getting this out! Loved it
I absolutely love the quality of testing in all this mate
You've saved me a lot of trial and error
That’s what I’m here for!
@@Darkwingdad Found out something that might be handy for your non-US viewers
Bondo = SCA in Australia
SCA is a car-parts store called Super Cheap Auto; they seem to rebrand a fair few products from the US
When I went to try and find some Bondo minimum cost to even get a small amount here was like $150Aud vs $20 at Super Cheap Auto
Thank you again mate
@@BirnieMac1 well you just made a lot of people happy, I’ll definitely spread this message. Aussie Aussie Aussie…..
Dude! Awesome video! I searched YT on the best spray paint filler and I got all I needed from this video. It means a lot to me to find Information about spray fillers. I've been using the wrong product. Sorry, I'm just excited about this. I've subscribed. Keep modeling and I'll keep watching. Thank you for taking the ti.e to create such a great video. I know how time intensive it is to video, edit, commentary, and most of all the TIME it took to put it all together. Thank you.
It was a journey doing these tests, but I do them for comments like this!
Great video man! Extremely informative. I've been a Duplicator filler primer guy myself for years but I might have to give the Bondo filler a shot! Thank you for the video and hard work explaining everything.
Thanks Chris! Someone had to do it lol! I also subbed to your channel, mighty fine work sir, let’s get you monetized!
@@Darkwingdad Thanks man I appreciate that..really means a lot! Just subbed to yours also and I look forward to more of your videos and learning a new trick or two.
Really cool. Thanks! The rustoleum has been my go to but gonna try the bondo. Cool info.
Rusto is one of the worst for wait times. Try upol or bondo & thank me later
I have been very happy with the duplicolor filler
Great test
Thank you!
Nice. Great test. A few things that I would factor in as variables however are cost and availability. 2 in 1 Rustoleum for example is $11 here in Canada, but it is actually kind of difficult to find. Duplicolor can be found, but only at Canadian tire and is $18. I've never seen the other ones.
I realize we're all in different places, but cost is a factor in my opinion. One other variable I would look into is post cure durability. I'm currently half way through a Scout Trooper helmet and I've already dented the primer (2 in 1) on a few occasions. I'm curious if the overall hardness of the primers is different once fully cured.
Finally, I think one other variable I would factor in is wet/vs dry sanding. I wonder if any of them perform better under those different techniques.
Thanks for the input! I did do a pricing & availability rating in part 1. A cure test would definitely be a great post test to do which I’ve thought of. Great minds think alike!
Thanks for really explaining the difference between each product. And to think that i almost used Rustoleum.
I’ve added a few videos of upols new line, they are really solid! Check those out as they are available at autozone!
I looked everywhere for the bondo spray. Dont see it anywhere. One source shows that it was discontinued. Bummer
You can get it directly through 3m
Also this is a sub company of 3m amzn.to/46yTcyN
Great videos, no wonder I go through so much sandpaper, I will definitely be moving away from the Rustoleum Filler/Primer for my 3D prints.
It’s definitely beneficial to move towards a solvent based primer. Everything is so damn expensive nowadays it all costs about the same too.
Nice video, don't forget the PPE with all that fine dust. 👍 we need darkwing dad tips to be healthy 😆
All joking aside when I was spraying I was wearing a respirator & when I sand I always wear a mask, it was just hard for the short time I was sanding/talking. But ppe is always important
I hope you can answer this but it may be beyond the scope of this test. What if I have already used Rustoleum Filler Primer on my 3D printed armor & done light hand sanding. Is it possible to add another filler primer type/brand or would that cause an improper chemical reaction/orange peeling? I've heard Rustoleum & Krylon DO NOT get along well together.
You can you just want to be careful and give the rustoleum a few days to completely cure & make sure it’s sanded down a good bit.
Would love an update comparing Bondo with the othe ones you showed in later videos like the Autozone ones 1K Primer, Upol ones. Thx
Slowly in the works lol
seems like i would go with the krylon for more detail work and bondo for the heavier and flatter surfaced. i have only used the rustoleum 2:! and man did it clump even days later
I honestly don’t know how people use rustoleum! Once you get the spray technique with krylon it really isn’t all that bad! And bondo, yea you can’t go wrong with it. BIG tip which I didn’t mention, a water based primer is ok ON TOP of a solvent based(krylon over bondo) but solvent based on top of water based you want to give adaquate time for the water base to fully cure
I just need a decent flat black spray paint. The Rustoleum 2x goes on too thick. Any suggestions?
Thsts bc the 2x is primer & paint.
Try duplicolor or krylon they aren’t as heavy of a paint. I use both in satin for busts and they are great
Hey! I just today watched your video on using upol 1k combination and wanted to basically exactly replicate your process for sanding and filling prints but unfortunately came to discover that the bondo filler primer spray had been discontinued. What would you go with as a second choice? Have you found anything remotely similar?
Yea I just did a video confirming it’s being discontinued. I’m doing a whole new video with new filler primers to compare to Bondo. For the time being upol filler primer (orange label) is the closest!
What's your usual order of operations for sanding? I did one quick pass of 80 grit with a power sander on this part and one layer of primer. The can says to do 3 layers. Wondering if I should do 2 more layers or move up in grit sanding by hand after 1 layer of primer in between each round of sanding. Or do you do the 3 coats in a row still?
First things first always use a putty. It is going to speed up the process immensely. Do not rely on just filler primer, it’s a step, not a staple.
Sand with 80 followed by 120 (80 leaves the surface gouged up) apply putty, sand with 220
Apply filler primer
Sand with 320
Repeat as needed.
I have several videos on how utilize a proper putty will not only speed up post processing but also improve your quality
@@Darkwingdad I did brush on a mix of spot putty and acetone on a helmet. Seemed to work well. Thanks for the info 😎👉👉
@@ImmortalReaver nice, that’s a great technique. What filler primer are you using?
I’m new to all of this but do you need a mask when applying the primer? if so, what kind of masks should one look for?
Yes, all these primers contain thinners & solvents a 3m respirator is best but if you have a spray tent & are outdoors you can “cheat” with a 3m dust mask that has the filter on the front. Some with argue but with a exhaust fan & being outdoors it’s ok in a sense. If indoors 100% use a respirator, if you need links let me know
it feels good to know youer not stupid , lol i used rustoliom and lost my mind because of how long it took to dry to matter how light of layer i spray , now after watching you i got to know why ,
FYI, if you guys wanna speed up the prosses place your coated models inside of any UV light machine i have one form my resin printer and i managed to make it dry in almost 2 hours instead of 2 days
well without UV it took more than 2days .
thanks a ton for this amazing Video man .
Appreciate the feedback, I honestly don’t know why anyone can use rusto. Unless you have 4-5 builds going on where they can sit for days & overlap there’s so much wasted time & frustration with using rusto primer.
@@Darkwingdad ikr , well i asked some" expert" with painting and he told me rusto is the best among what he have tested :/ any way lesson learned 😁
@@mnr3d please tell who lol
Dupli-Color FP101 Scratch Filler Primer is the same as 29/40??
101 is very similar to refinish & dries like the 2 in 1, I wouldn’t be shocked it it’s a relabel bc I haven’t seen refinish available anywhere
Yep. Can't rush primer fillers. For me, 24 hours, minimum. A week even better. Oddly enough. I wet sand and it does reduce clumping and clumping happens more to finer sandpaper so got to be very gentle
I just hate introducing water into a semi porous filler, slows down progress that’s why for me bondo is the best. Sand it with 400/600 & it’s buttery smooth
Has anyone used Simoniz primer filler?
do any brick and mortar stores sell bondo filler primer?
Select ace hardwares have them. You can also order on ace online & pick up in store!
Sun really do make a different. I used rustoselum filler primer in 65 degree no sun and man even after 24 hour it doesn’t want to sand.
Even when I used it here in the FL summers it would still gunk up being in a 100* shed after 10 hours. It’s just a bad product & a huge reason so many people fail when finishing 3D prints
@@Darkwingdad I did amazing filling all my scratches but agh! I need it paint my bumper but I can’t without sanding this primer down
@@Darkwingdad I’m going to attempt to water sand it even though it doesn’t say I can.
Isn’t the bondo discontinued now?
New video up this weekend in regards to that topic
@@Darkwingdad Oh, you're amazing, thank you! I'm excited to see it!
@@jessd.294 video is up
I've never liked Rustoleum products..
Waterbased junk. Much better products out there.
Just used Rustoleum Filler Primer today and it's total garbage. 3 hours in direct sunlight and still clumpy junk.
It’s rough, did you use the new labeled one?
