I prepped several aluminum test panels and a piece of epoxy resin sealed 1/16” aircraft ply. Two coats of white epoxy primer for the first step. My plan is to take one of these all the way through final top coat and the others will only be coated with each step in the process. So I will end up with a primer only panel, one with primer and the white System 3 waterborne polyurethane, one with the System 3 poly with SEM fluorescent additive tinted clear coat, and one that’s been painted with the System 3 poly and only clear coated.
Later on I’ll be soaking these test panels in acetone, lacquer thinner, and high Nitro fuel. The key to getting a paint film to breakdown prematurely, if it even will, is to scratch through it down to the bare substrate allowing the solvents, chemicals, etc to also attack it from underneath.
I’m curious to see the results.../monthly_2018_11/IMG_9446.thumb.jpg.9bc3053f8c55f19935c074ca519d13a0.jpg

The other products that will be sprayed on my test panels.
This epoxy primer is really awesome stuff, I highly recommend giving it a shot if you’ve never used it before. And it’s about 1/2 the cost of Klass Kote, sands like a dream too.
