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.

Next time don't even bother with the epoxy finishing resin....go straight for the epoxy paint, clear with satin hardener as you glass bedding resin. Your finish will be lighter, just as strong as finishing resin and just as fuel proof. Your pot life is around 12 hours minimum so you have lots of working time
