actually there's two different kinds. One kind you can buy in wal-mart for like, $5...it's light-grayish tape and it has red plastic backing. This is good for small stuff like headlight/taillight covers. Then there's a black tape with red backing..this is stronger and is good for bodykits. I still haven't found this in any store tho...I gotta ask my bodyshop about it cuz they used it a couple of times.
