AAargh! Monokote and contours!
You know, I've been using monokote for some twenty years now. The last time I used it it wouldn't shrink and compound curves were near impossible to do. I switched to Oracover on the one I'm finishing now and love the stuff. Oracover makes Ultracote and is about 4 bucks a roll cheaper. Thanks Minnflyer for turning me on to this stuff.
