I rattle canned my savage rear bumper and skids right when I got them. Used a good cleaner, then self etching primer (2 coats), then rustoleum bed liner in a can (4 coats). I was too cheap to go the powder coating route and I knew I was going to continually scratch them up so it works but definitely have to set it's not the best. I'm going to have to touch everything up pretty soon here cause they're getting rusty at spots... In the end it will cost more to rattle it with all the touch up paint I'll have to keep doing but it works...
