From the Ebay photos I've seen, the Matrix bumper protector folds over the edge of the rear bumper just a bit. Is the protector molded to do that or is it just a flat strip of rubber than you fold over the edge?The reason I ask is that I have a Grand Caravan and the rear bumper has some scratches that would be perfectly covered up by the Matrix cover...that is, if it's not contoured/pre-molded. Thanks.
