Last winter in Utah was harsh on my Jeep bumper. What are the thoughts on getting rid of this, so I can repaint it. I need something simple, as I have very limited tools at the moment, including what's necessary to remove it from the vehicle. I'm going to use textured paint.

Wire brush and drill perhaps?

Take a knife and flick off the loose paint. It tends to adhere well around the perimeter. If you use a wire wheel, it will thin the paint and primer, which would be fine if you feather some paint on it quick. For the rust, there's some stuff called "Evaporust" at Tractor Supply. Soak a rag with it, and let it sit on the rusty area for a few hours. It isn't real aggressive, and won't lift more paint, but will wipe the rust away.

Probably not what you want to hear, but there is more rust that you can’t see under the paint. I’d start with a flap wheel on an angle grinder…clean up the pictures areas and start taking the paint back until you find clean metal. Then I’d hit the rest of it with an orbital sander to knock down the texture and paint with POR15 topcoat.

This right here.

Looks like a fabricated steel bumper as well? If so I'm betting that's powdercoat and there is more rust hiding underneath that you'd imagine. The powdercoat tends to trap moisture behind it once it's cut in any way causing the rust to spread out of sight til it gets thick enough to push the PC away to where it flakes off.

He might come away OK on picture 1, but pictures 2 and 3 have at least 3 times or more as much rust underneath the coating as is seen in the pictures. This is why I hate powdercoat. Rattle can "hammertone" or some sort of textured paint is a way better idea as it can be touched up without looking like it was touched up...which is especially useful on off road armor that gets beaten against rocks.

Pull it, sandblast and recoat is the right way to do it...

There is rust on the back side, and mounting ears too.
