Oh no...here's comes the resident Raptor liner guy!
My entire vehicle is going to be Raptor lined shortly (it's a type of bedliner). For folks that might think it's little extreme for the entire body, it does give nice contrast and compliment if you do only fenders/bumpers/etc.
It comes in spray cans now and is a one-day job, easily. Bumpers are super easy to remove with just the carriage bolts holding them on. Clean, scuff them, wipe them down with water/alcohol or acetone and spray adhesive promoter. Two light coats and you're down. Very similar procedure to a rattle can paint job, there's innumerable YouTube videos that will give you plenty of good (and horrible!) advice...
