I have always hated Monokote and probably always will. It is by far the most difficult of the films to apply. What it has that no other covering has is very vivid colors. Oracover (UltraCote) looks dull next to Monokote.
I've had no problems with Monokote being brittle with the exception of some old transparent stuff that was in non-climate controlled storage for about 10 years and was already about 5 years old before that. When I got it out of storage it crumbled in my hand into pretty little flakes.
