Dan....Know about lacquer in heated car. Was not left very long, but had the imprint of my seat material. It rubbed out OK but I never did it again. Can you comment on the epoxy paints for our purposes. I don't think I would spray them over lacquer, but what about enamel or latex. Should we use epoxy over epoxy or can we get away with latex. (more color options). Another question to try your patience.....Can pearl powders pe added to clear epoxy. Thanks for your input into the subject. Dave
Epoxies are among the strongest finishes available. Watch the thickness though, they can be quite heavy. They would work great over lacquer primer, over CURED enamel ( depending on the enamel, that can take longer than you think) and fine over latex. Epoxies are slow to crosslink ( cure ) so during the application process you shouldn't have reactions with underlying products. Lacquer can work over enamel ( not recommeded though ) as long as the enamel is cured. Oxidation is a slowwww process so that is what gets most people in trouble. The enamel isn't chemically stable and solvent ( even itself ) can cause problems.
Pearl powders ( great stuff ) can be added to any clear product and sprayed. The amount added depends on your spraying style and taste - a little goes a long way. Don't add too much or it can get a little difficult getting a even, blemish free finish. In the automotive world, pearl is added to what is essentially clear basecoat. A pure clear overlay is than added on top. That way when you rub the finish you are polishing raw clear, not pearl containing clear so the finish stays nice and even. Doing it that way on our planes would add weight though so that's the trade-off. Again, our planes don't see the outside enviroment 24/7 so we can alter the process somewhat to our liking.
