I'm looking for some advice on how to build my own rear quarter panel patch. The body on my car is pretty straight other then the typical rear quarter rust. I'd really like to do it myself but there doesn't seem to be any patch panels available for the grand prixs. How hard is it to build one yourself and can you guys point me in the right direction to get started any tips or tricks would be much appreciated I'm new to body work so any little bit helps.
