I've posted this before but here's my experience with Plastidip:
I had my window trim and front grilles plasti-dipped this Summer -- huge hail storm came, and my car suffered close to $16k in hail damage. The trim itself was literally in pieces, and the Plastidip is all that was holding it together. The stuff is bulletproof (or at least grapefruit-sized hail proof).
