I think the problem is going to be that you will want to put it over paint. It doesn't take that much heat to activate it, and it would probably work on bare plastic. There is also a liquid "Monokote Trim Solvent" that will make it stick without heat. I suspect that either the heat or the solvent would ruin a paint job, tho. Looking forward to the results of your experiments, I have a bunch of scraps of it too!
