So4me: Very nice.
What primer did you use? Did you spray it or brush it? Did you sand it dry or wet? Are these fiberglass cloth over balsa?
Did you add anything to the latex (acrylic) paint, like Floetrol? Did you apply the paint by brush or spray?
I have a request: Take (a small quantity) of the Top Coat, and mix in an equal quantity of acrylic wb (latex) paint. Brush that onto a test piece, and after cure, subject it to glow fuel and tell me if it holds up.
