so here is the thing.
This particular bit of rust is pain in the ass. I took it to a rust repair, he told me it's a double layer, the second layer looks very clean and he could cut and weld which requires the fuel tank to be removed. But he insists that using plastic bog is easier and much cheaper, and could be more rust proven as well.
He also mentioned doesn't matter is welding or bogging. The rust might come back later because of the double layer, and he couldn't put fish oil in it.
another question:
Is there anyway to strip the bumpers paint, so I could get someone to restore the bumper to factory plastic with no Paint?
any thoughts?
