I have a 02 cav that im going to put a 03 ls bumper on...but i wanna shave the tag box... cav parts around her are a dime a dozen in junkyards so i was going to buy 2 cut the one up and section the peices in for the tag... would fiberglassing the inside workto hold it together... im not fimiliar with the fusor products...
fiberglass doesn't stick well to the ABS or whatever the LS bumper is made of.
it may work for a while but will eventually fail
