My tire carrier has pretty good powder coating. Only issues I’ve seen is rust started around the welds by the hinges. Must have been thin there. Also it is all rust inside where the bolts mount to the tailgate. It’s like they only powder coated the outside surfaces. I was thinking about repainting but that would mean taking it all the way back off.

Unfortunately, you can't really powder coat the inside of a part. There are things that can be done to help prevent rusting but not powder coat. Taking it off and spraying frame paint inside will help but it is a LOT of work.
