A common thing with these bumpers seems to be galvanic corrosion on the rear of the bumpers where the shock mounts. As the paint and leftovers from chrome plating were beginning to fail, I went ahead and pressure washed it well, scraped off what loose bits were still on, and put two coats of Rust-Oleum Professional on. The paint took very well and should insure the bumper lasts a lot longer. Where the shocks mount will also be coated in some grease just to make sure. I still need to paint the light wells, but I intend to do that after it is mounted.
On one of the backup lamp wells is damaged, though I have cut and bent it back in to a lot better than it was. It is not visible once fully installed. …And only now have I noticed I failed to take pictures of the unpainted bumper. Huh.
