Well, a couple days ago, I cut out the plastic and metal tabs for the bolt on the rear bumper(due to rubbing). I used a cutting wheel, which didn't do the cleanest job, but now I don't rub.

My concern is mainly for the bare metal. I already cleaned it all with isopropyl alcohol and applied a few coats of an anit-corrosive rubberized spray. Covered just about most, if not all, bare metal spots. I'm curious as to what you guys did, and if some of you have done this years ago, how are the quarter panels holding up? Any signs of corrosion?

The coating I put on there is 'paintable' so I might throw some paint on top of it, not sure.

Any help is very much appreciated!!
