I just did a "new" rear bumper I picked up. I took a sanding wheel designed for removing paint/rust to the rough spots, and it cleaned it up nicely. Then I threw down some rattle can primer and finshed it off with a can of duplicolor bedliner. Turned out nice, and seems like a solid finish. Be sure not to do the duplicolor over an aftermarket paint. It did fine on the primer, but bubbled on the semi-gloss I put on the hitch.

This maybe too expensive, but I have been looking at the Por 15 products to take care of some rust problems that I have on my Jeep. I don't know how well it works on bumpers, maybe someone else can chime in. sorry
it's just a generic bedliner. Like a Rhino Liner Bedliner, but comes in a spray can for $7. I figured if it doesn't work, it was only 7 bucks. but if it's meant to be a bedliner and see some abuse, I tihnk it'll be fine on my bumper.
POR15 is good for rust and supposed to be rockhard, but I think it's a bit much for a bumper. If you got the coin, go for it. I decided to go the rattlecan direction.

Lambar, Por 15 is great stuff. I have used it in my tub before Herculining, also on Frame Rails, and Spare Tire Mount. It is worth every penny. I just ordered more for other miscellaneous applications.
POR 15 doesn't adhere very well to painted surfaces. Need to try and take as much of it down to bare metal as possible. If the rust isn't too bad, you can shoot it with muriatic acid and the acid will eat the rust away. It'll also etch the steel for paint adhesion. If the bumper is painted, I would probably just scuff the paint, run a flap disk (in a grinder) over the rusty parts, and then shoot POR 15 Chassis Black over it (2-3 good coats). That should work out pretty well.

I posted the same thread a while ago and somebody recommended Krylon hammer paint. I think thats what it is called. It has "hammer" in the title. He said it works great. I havn't used it yet though. I'll look for the thread.
Found it. Rustoleum, not krylon.

Looks mean i get compliments on it all the time with people wondering what i used because it looks so good.

anyone used the muriatic trick before. i have like 10 gallons of it and i need to do my steel bumper. anyone know if it will touch rubber or anything to look out for. i use it to acid etch floors now and then for bonding. never thought about using it to etch metal tho.
