A secret spray putty? A new high build primer for sanding 3D prints | smooth layer lines easy!

I like it!

For miniatures, would you recommend the Upol or bondo primer to keep details?

this is going to be game changing for my 3d printing.....thank you!

I just picked some of this up and tried it, I did not get as good of results as you did but maybe I needed to use some glazing putty first? I'm new to fdm and post processing but I first sanded everything with 120, then primed with the upol, let dry and added another light coat then sanded again and reprimed. still getting lines and it doesn't look all that great =\

I love your videos man you definitely get rid of the guessing game for us but which is better this new upol or the bondo?

love your work :)
I'm planning to 3d print a project out of PLA with 0.2 layer Hight and make it look like a metal.
I have sanding papers with grids up to 3000 grid. I noticed you only done dry sanding. Is there a point or grids you would recommend wet sanding if I would want to carry on up to grid 3000?
Should I spray the project only 2 times after the initial sanding or later on between the sanding stages as well?
Did only once similar project with Bondo putty but it was very labor intense. This looks much more efficient :)
Planning to get the Upol High 5 Primer GREY 450ml Aerosol High Build as the one your testing is hard to get in UK

I have some of my prints with wood glue, to cover the cracks... wondering if you think this will be ok and will apply onto wood glue no problem? or maybe Epoxy resin?

Great review! I’ve actually decided to use this product on an old Italian acoustic guitar. I’ve gone the traditional route using vinyl sealer and nitrocellulose lacquer. The soundboard of this instrument was made with a questionable quality wood laminate, the top layer being spruce. Sanding resulted in some spots where I went right through that spruce, revealing an ugly layer of horizontal black corduroy-like material. This not the stuff they build most good quality soundboards with. I used a combination of epoxy putty and CA glue to cover these areas, followed by lots of sanding. I thought I successfully filled all the defects. Then, after one coat of white vinyl sealer, and two coats of black gloss nitro dried, all those defects stuck out like a sore thumb. Totally frustrating. I planned for my next project, a solid body electric, to try Dupli-Color Perfect Match products, just for fun. There are those who say that auto body finishes steal some of the resonance from the wood. On acoustic guitars? Probably. But I’d say they’d best consider Leo Fender’s use of DuPont auto paint on some of his guitars built in the early sixties. They also might consider Eddie Van Halen’s wailing “Frankenstein” guitar, which was finished with bicycle paint.

Tomorrow I’ll sand off the finish on this acoustic, then try a few layers of this Upol product. Your demo convinced me to choose that route. If it yields a nice flat, level surface, all that’s left to do is put down some Dupli-Color Perfect Match for the color coat, followed by some clear coat. I’ll let you know how it goes.

Okay now I’ll have to give this a try hahah

I need to find a few cans of this ASAP. I have new helmet print and a Arc Trooper blaster to work on.

Didn't know what video to comment this on I saw you can use wood filler to fill in later lines and it's brilliant for sanding can you recommend any for me in UK lol

You are awesome, I hv been thinking of the fastest way to get my print ready to go without having to do much

Any suggestions on a paint brand to use along side this? I have mostly been using rustoleum

Did I just hear your name mentioned on the 'Knock Once For Yes' podcast?

So now the big Question here is wish one is Better, Upol expert sandable prime or Raptor Pro Universal Gray Primer !!!!!!!!

What happens if you don’t pre sand it and just apply this first.

Grabbed a can this afternoon to try and sand/spray our first piece. We only sanded with 80 grit and went ahead and sprayed 2 coats. Should we have done the 180 as well before laying down the first spray? Drying now so we'll see how we fared, haha. Having a great time and learning in the process. Should we be sanding very heavy handed? I see you scuffed it up really well.

Thanks and Happy Memorial Day Weekend!

Since this is a primer. Once sanding you can just start spray painting? Dong have to prime it right?

Congrats on 10k and well deserved, lovin these vids 😁 is this available in UK ? Apologies if already been asked.

I did your UPOL Dolphin/Accetone brush on mix, followed up with the Bondo spray filler after a sanding. And holy crap did it change the game.

How does this compare to the Raptor 1k primer you recently reviewed?

Thoughts on Seymour PBE Filler Primer?

Do you wash the print? After every sanding then add this spray.

Currently printing R5-D4 and on the body portion. For $9.99 a can + able to use coupons, I will be trying this out. Those $20 cans just didn't seem worth it as It would cost a ton to complete this project. Been using Rustoleum 2-1 sanding primer as of now.

Just bought some man I'm testing it out right now so far so good.
5 min later...This stuff works pretty damn good it dries really quick too, it's actually pulling up on me where I am I'm behind the building so that might help.

Man, that's awesome!! Thanks for doing these videos!

I don't like mixing and spraying putty. Even brushing a mix on is kind of a pain. I'd personally much rather use a rattle can. I already started using the normal upol stuff. I'll definitely be on the look out for this stuff next time!

Anyone know if we can find this primer in Canada? I looked many places and I had no luck with this brand.

Congratulations on 10k homie. Keep grinding and putting out awesome and helpful content.

So would you say that this eliminates the need for the spray putty step? Just spray this stuff on, then assess if putty is needed thereafter?

Wasn’t able to find this at my local O’Reily’s 😢

Awesome stuff

what an effort man!!! thanks a lot
sad couldn't find it on amazon :(

Dang, I was just at Autozone, now I need to go back!

Good to know about this. Thanks!!

Sweet.

thanks pal , great info as usual , i have a trip near the local Auto zone , i will check it out

Sheeeeeah! Were going to need a head to head for all these filler primers and putties! Great work as usual 🔥🔥

As everyone says, thank you for doing the testing that you do! I appreciate the shout out as well! Happy to help.

Thank you so much for all of your testing and sharing this wealth of knowledge with us! I'm a proud student of DWD University

Awesome! How does it compare to raptor primer? Love the new intro btw

I do flocking also LOL

I still want to see the 2K primer?

So question is….Raptor 1k Primer or the Upol Expert Primer?

DWD is the man! I've never seen any other maker put so many man hours into trying all the different methods to hide pla lines, and report back to the 3d printing community so consistently 🤜🤛

Damn! would you say this is better or on par with the upol filler primer? my local store has both in stock O.O

You sir, are the bleeding edge.
