i am currently just about ready to spray clear coats on a guitar body project...i have used a hi gloss oil based enamel for solid colour and want to spray polyurethane clear coats over it for durability.....i tried it on a piece of scrap and found that the solid coat wrinkled when i put on the polyurethane clear coat....why would that happen??
the last thing i need right now is for the same thing to happen on the guitar body after putting so much work into it.... thanks for any input zz zz
Karma, dude. Ruining a perfectly good finish with polyurinestain? It's gotta be karma. Oh, and a slightly wet surface underneath, or possibly a mismatch in solvent bases of the finishes, like lacquer over enamel or vice versa. Try it again after letting the finish settle, dry, and cure for a week or two.
Better yet, ask your local paint store for a pair of -compatible- finishes.
I hear that. G'luck.
- Ever wonder what the speed of lightning would be if it didn't zigzag? -
Because spray urethanes often (always?) have solvent(s) in them other than plain old thinner and those can attack other finishes.
Another possibility: if the color coats were pretty thick and not really dry they could have acted like "wrinkle paint"...after putting on the poly and it dried the color paint continued drying and in so doing shrunk causing the wrinkles. I'm betting on the solvent theory though... ______________________
It would. You might try another scrap just misting on a *very* light coat of urethane and letting it dry as a barrier. Or using another barrier...maybe brush on poly?

It's the solvents in your poly and and any workaround is going to be more work and less satisfying than it's worth.
My Suggestion: Call Target Coatings at 800-752-9922 and order a quart of their 9000 series Super Clear Polyurethane ($19.95 plus ship). If you're willing to pay the freight they can have Fedex deliver it to your door next day.
A big plus is that it don't stink :)
The usual disclaimer applies, I'm just one happy customer. Target has really pushed the envelope with their formulations, to the point that they now have a workable product for almost any wood finishing application.
many thanks..i am thinking of staying with the hi gloss enamel and forget about clear coating....prolly just shoot a couple more colour coats rub it back and buff it out ,,,, zz
