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
