Sorry if this is a dumb/obvious one- but is polyurethane/polyester from a spray can a thing that exists? I can find clear spray paints advertised as being polyurethane, but no opaques. Seems like everything from Duplicolor/Rustoleum/Krylon is in fact acrylic lacquer, or am I mistaken?

Poly in Spray Cans?

Re: Poly in Spray Cans?
The Duplicolor/Rustoleum/Krylon is mostly enamel. You need to look at car paint, I have bought clear poly in a can from an auto paint store, so I'm sure there are colors. You have to find a "real" auto paint store though, not an Advance, Autozone, Pep Boys kind of store.

Re: Poly in Spray Cans?
I used Duplicolor 'true match' or whatever on a guitar a few years ago which was described as acrylic lacquer (I think other Duplicolor series might be different.) In any case it dried and polished which I think enamel wouldn't do for several months at least?Originally posted by King BuzzoI love when people come up to me and say “Your guitar sound was better on Stoner Witch, when you used a Les Paul. “...I used a Fender Mustang reissue on that, dumbass!

I tried once with common cheapo (greek) acrylic (oil-based) spray and it was very soft, some months later it became like relic

Re: Poly in Spray Cans?
The 2k products are poly. Duplicolor is mostly lacquers. I have been using them for most of my refinishing.
You don’t want to use a poly over a lacquer

Re: Poly in Spray Cans?
I used the Duplicolor Acrylic Lacquer on my SG Junior build with great results. It took a while for the smell to settle down but it came out great. The goal was to have a Gibson faded style finish as I didn't fill the grain or anything. I rotated between about 3-4 cans while I sprayed and kept them in a bowl of warm water to eliminate cold spits. As I felt one can get cold, I would change to another one. It helped that the nozzle is adjustable on the cans for horizontal or vertical spray pattern. Take your time and start the spray off the wood and move on to it in a steady motion applying light coats.Last edited by ErikH; 11-21-2018, 09:08 AM.

Re: Poly in Spray Cans?
Thanks - basically the guitar I refinished in Duplicolor ten years ago has checked an reliced; I have not always been gentle with it. Some people might like the look, but I'd actually prefer it to be h-bomb-proof, so looking into options for a DIY poly.Originally posted by King BuzzoI love when people come up to me and say “Your guitar sound was better on Stoner Witch, when you used a Les Paul. “...I used a Fender Mustang reissue on that, dumbass!

Re: Poly in Spray Cans?
I have used so many materials.... only now I'm finding the recipe that works for me. I start with 2K because it's fast. like, really, really fast. I spray a guitar in 8 hours; that's 9, 10 layers or so (2 full cans). Then I cure each side of the guitar under an IR lamp (twice 30 minutes) and then I can sand the entire guitar again. so, 9 hours since I started, I can sand and buff the guitar if I wanted. Helas, 2k automotive paint in a can is notoriously soft! It's tough as can be, but it is soft because car finishes have to have some flex in them. So, after it's sanded, next day, I'll start the finish process but now with nitro. One can of nitro. done.
The 2K is my porefill as well as sanding sealer. the nitro gives the most beautiful gloss I've seen. I don't know, but the material glosses differently than poly, 2K or acryllic.
I have used acryllic too and sometimes still do, when the guitar has to leave the shop fast. The acryllic I use works really well as an undercoat for my nitro if need be, because they use the same solvent.
Hope that helps?

Re: Poly in Spray Cans?
Hey orpheo, I did some work with of-the-shelf acrylic oil based paint + clear coat and this thing hadn't held, after some months it starts to melt. How long Nitro needs to harden? Does it hold? Is it durable?
