the road salt here in Iowa has recently started to eat my rear bumper up. I know this is a common issue for these Jimmys and Blazers to get rusted bumpers. I took some 80 grit and sanded all of the bubbles down, attempted to smooth it with 240(its all I had) Put some rustoleum primer on (that grey stuff) and then came back a week later, taped it off and put some herculiner up on it. was this too much of a redneck fix lol, what else could I do for minor rust spots that may occur again

 

Looks good from here.

Did you address the inside of the bumper as well? If the outside edge is looking like that, then the inside will likely also need some attention.

 

I did not look at the inside, I will have to pull that off when I get a chance, my 4x4 is giving me hell at the moment lol

 

Not trying to make more work for you. Just wanted to note that the inner curve of the bumper tends to accumulate dust and debris (especially if you go off-road) which can trap moisture against the bumper.

It's always good to see people trying to keep these older vehicles looking and running nice.

 

its no issue, i like suggestions on things that will help, afterall, its pointless for me to fix that outside when the inside will rust it out again and come through
