***thread title was supposed to be "repaint over original finish"**** auto correct is a pain!

So I have been doing some research because I want to refinish a 540r that I repainted last year. I accidentally bumped it pretty hard... And ruined my paint job. I came across this company who makes high quality automotive spray cans and something called a 2k primer and 2k clear. Kustom Canz is the brand and their colors are outstanding looking. I can't seem to find a bad thing about them.

The guitar has its original urethane paint under my repaint. I can easily strip off my repaint, I've done this once before with the same brand paint I used in the past. I used duplicolor perfect match primer, and base coat. I don't know what type of primer the perfect match is. But the base coat is an acrylic lacquer. The clear I used was minwax gloss clear lacquer.

So my question is... Should I use an adhesion promoter instead of a primer since urethane is essentially plastic? Or just stick with an automotive primer? The kustom Canz site does not specify what the base coat paint is... I am going to call them tomorrow... They recommend using their 2k primer in a can which is a primer with a catalyst activator, but they currently are out of stock... And it's $20 a can. The base coat requires a 2k clear which is also a clear with an activateable catalyst. This system seems amazing. I did a youtube search and it looks like a 2k clear makes anything extremely durable... Even regular rust-oleum spray cans.

Update. So I emailed the manufacturer and they got back to me. Their products are all urethane in a can! The reviews on this stuff are great btw. I shouldn't have to use an adhesion promoter, their (or another brand) 2k primer is fine. Even an automotive primer would work. I don't know if anyone even cares about the subject... But this to me is a game changer for anyone who doesn't have the equipment to paint with a paint gun. The fact that there is a catalyst is amazing. In 24 hours it's hard as a rock... It can be wet sanded, buffed and then reassemble in a weekend!

Yep, this is great stuff if you don't have an HVLP setup, I've done it several times with excellent results. After stripping (or just scuff sanding if the original finish is poly) I use an automotive primer, then automotive base coat for the color (my local auto paint store will custom mix colors and load in a spray can for me), and finally finish with 2K clear. SprayMax brand is what I've mostly used, but be very careful with it and mind the warnings, it has isocyanates and can seriously injure you! 😵 What's great about going with all auto-grade stuff is you could spray everything in a single day and be ready to wet sand/polish the next like you say, very different than nitro. I have a spray rig now, so mostly mix my own, but the cans do a great job too! Glad you found a solution that works for you.
