@PapaWhiskey33 hit the nail on the head. That thread not only has some great tips on finishing the bumpers (by other members, mostly) it has some good photos of the unfinished bumpers, and the interim primer coats, as well as paint suggestions.What is the procedure for finishing these? I have no experience in painting bare metal.
I seriously considered powdercoating them, but listened to all the good advice about touching them up afterward, and glad I used paint instead.
