StoleN GuitaR Posted September 1, 2005 Report Share Posted September 1, 2005 Hey, after ing lots and lots of topics. I can't find one that answers my question. I am using an Aerosol Acryllic based Car paint, and I am wanting to finish it with a hard clear coat. from what i understand Poly's are one of the hardest coats and seem to protect whats underneeth. My question is: Can Polyurethane clear be used OVER an acryllic based paint as a clear coat? Also, the Headstock Vynal I have can only be clear coated with Polyurethane. Thanks in advance!!

axemannate Posted September 2, 2005 Report Share Posted September 2, 2005 You might be able to get it to work without a reaction if you dust on the poly MANY times allowing 15 minuites flash time inbetween dustings before you start to put it on normal.

StoleN GuitaR Posted September 2, 2005 Author Report Share Posted September 2, 2005 I don't think I'm 100% up with spraying lingo just yet lol So if i do a lots of dust coats with 15 mins between dusting coats? then after it starts to build up then spray it normally?

axemannate Posted September 3, 2005 Report Share Posted September 3, 2005 Yes, after you get it built up, just go ahead and spray normally. As long as you dust it with clear a bunch of times before you clear normally, everything SHOULD be fine, but you still might want to do a test.

lovekraft Posted September 3, 2005 Report Share Posted September 3, 2005 I don't know of any compatibility problems between cured acrylic lacquer and 2-part poly clear, but don't take my word for it - ask the guys you're buying your poly from. I know the HOK Shimrin bases are compatible with either acrylic lacquer or poly enamel clearcoats, but that may not hold true for everything. I have sprayed catalyzed auto poly over water-based acrylics (Auto Air) with zero issues and spectacular results, but that's not quite the same.
