David,

What your thinking of sounds similar to a tip I tried a couple of airplanes ago. I applied the .75oz glass cloth with Krylon acrylic. Went on real fast and easy, and sands real easy. Sprayed the airplane with Klass Kote. She looked great. Flew it a few times and the paint started blistering badly, especially where I had dark colors that would absorb heat from sunshine, and around the cowling and muffler. As it got worse, I called Klass Kote and got to talk with one of their engineers. His take was that the non-epoxy base was trying to breath and the epoxy said no can do. Next time around I went back to applying the .75 glass cloth with finishing epoxy, thinned about 40% with MEK. Went on easy, at least until the epoxy started to kick, wasn't too bad to sand, and seems to be a great base for the Klass Kote finish. No blistering in the summer sun.
