The bad rust is at the rear wheel lip flairs, solid floor boards and engine bay.
A rear Wheel
Near the passenger door
Both front wheel wells are clean.
I had in mind doing a little power grinding and then coating wheel flair lips with Naval Jelly or POR-15. Then covering it up with plastic ZR-2 or Blazer arch surrounds. However my neighbors Blazer openings are about one inch more in diameter than mine (20"-21"). The ZR-2 has 33" wheels and would be even larger.
EDIT: I need a tow hitch, would the one from the Tracker fit?
