Just tested a top coat for latex painted models that use glow fuel. It is a water borne Polyurethane manufactured by Cabot. This stuff impressed me so much I built a computer desk and sealed it with this product. I applied a top coat over latex and found out that raw glow fuel (I use 10%) left on this surface for 12 hours showed no signs of damaging the surface. Next test will be hot glow fuel. So far I like this stuff.
