Zumba,

Very nice.

I think with the higher end process of post cure or the process of calorific absorption will suck in the excess. I boat building you get fiberglass pattern showing through when you use dark colors bringing the temp over 140 which draws in the epoxy (calorific absorption). Problem with deep colors like black. Obviously just discussing a concept. Heard it first hand from a chemical engineer involved in boat building. Not a common concept.

I also vaguely remember that it might be better to have temps increasing to constant rather than the opposite, decreasing.
