In addition to what Campy mentioned, the Solartex pigment also tends to smear when hot. You'll have red and blue mudges all over that white layer. I'm doing my Aeromaster in white Solartex also. I plan to paint red and black stripes. I'm using automotive duplicolor rattle cans including their clear for the final topcoat.

(EDIT: I have now discovered that Duplicolor Rattle can Clear is NOT totally resistant to glow fuel and am planning to use DuPont Chromaclear, a 2 part urethane product for my plane. It requires a respirator. Sorry for the misinformation.)
