Three or four years ago I replaced the rear bumper on the '88 Cherokee. I bought from the dealer, and I thought I was buying a new bumper but I'm pretty sure it must be a rechrome, because the original lasted 20 years, and the replacement is already showing rust.

 

I'm wondering how it would work if I were to wipe down the rusty areas (which are mostly on the top, horizontal surface) with rust killer, and then apply a layer of that shiny silver tape that HVAC guys use to seal joints in ductwork. Does anyone know if that stuff would hold up outdoors? Is it stainless steel or aluminum?

 

TIA

Pretty sure it's aluminum, probably won't last very long, but nothing much to lose. Wish I could find a new OEM back bumper (but not chrome)....

It is aluminum. It wouldn't hold up to anything and besides it would look like hell. Best bet is to have it re-chromed and save yourself the hassle.
