Ok so i've been doing some research on grill blocking and this seems like it would be an EXCELLENT material for grill blocking, not just for me but for many others:

now we gotta figure out a way to get smaller rolls or just how much of it I want :/
edit:
Just called fedex kinkos, they charge by the square foot if you go to an imaging department, i'm still trying to figure out price.
Side idea: This would be absolutely PERFECT if you were to cut circles and simply stick them on your existing hubcaps, it would work for pretty much ANY hub cap so long as there are flat surfaces to stick it to!
