I came across this amazing coating that I wanted to try called
STEEL-IT. It is a polyurethane with stainless steel flakes in it. Because of the stainless content, you can weld right on it. I am going to coat my truck frame with it but for now, I sprayed my warn winch bumper. I have had a hard time finding something that will stick to it without disassembling it and having it powder coated. That's another cool thing about STEEL-IT, it comes in a spray can. The trophy truck guys have been using it and I have gotten glowing endorsements. There is a video with a friend of mine on their website.
