only had that happen once with some racing stripes. I installed some racing stripes on a kids car (3m air release vinyl) came out great and his buddy shows up with a stripe kit he bought and I tried to install it. I ruined 1 stripe (non air release, brittle matte material. just like you said) cost me $20 and I said never again.I tell them I don't install customer supplied vinyl. Simple as that. Some of that stuff I've seen is so, so horribly cheap. I've seen camo come in, non air release, no laminate, super thin and brittle. No thank you.
