Removed front bumper. I thought I'd better remove some rust that ran along a seam behind the bumper. I masked, then shot the bumper mount with paintable rockerguard to seal it up. While I was at it, I sprayed the inner surface of the bumper with non-paintable bed-liner. Finished by painting the bumper end caps and them mounting them to the bumper with an additional stainless bolt. The bolt runs through the tab that slots into the bumper.
