Hi Jerome

Sorry, forgot to mention! Its Monokote, I am a long time Ultracote user and thought I would give Monokote another try. For me at least I am very pleased with how it turned out, I didn't find it any more difficult to use than Ultracote.

Robert,

I used what was provided in the kit, I think the capping for aileron/elevator etc. is 6mm, the LE is thicker and also slightly beveled when you get it. I don't know off the top of my head how thick, but I can check later and let you know, but its thicker than 6mm for certain.
