Ill ask on the mil thickness. Its red vinyl with the other colors imprinted then they stick a layer of clear over the top. Very rigid decals they stick very good bud I have flipped up the corners or the tank scoop at the car was but is will stick right back down. I've ran them for a year and held up great. The clear makes them UV resistant and they are done in spot colors so like other decals I've seen look kinda like there printed on a home computer (pixelated)
