Default Rust behind front tire - Repair Help (56k Death)

Hey all. I'm working on my '99 - installing long arms & stiffeners @ the moment. Well, I pulled the plastic inner fender liner up front & came across rust. I'm wondering if you can give me any tips on repairing it, cutting it out, etc. It is actually *above* the floor pan. Since pictures are better:

Passenger side, looking toward the rear behind the tire (plastic cover removed) The red arrow is pointing @ seam sealer, no metal over it:


This is a closeup of the same area:


This is the inside, with an arrrow pointing at the area where the hole is:


And, lets look at the driver side. I hit this w/ a flap disk and am *thinking* it is good to go w/ some rust treatment (POR-15/etc.) and paint. Thoughts?:


Closeup (the brown area *under* the rusty crap is paint, no rust there):


Opinions? Do both sides need cut out or do you think I'm ok w/ the driver's side?

Mine were a lot worse than yours.


Your driver's side just needs two coats of POR15, and two to three coats of top coat enamel. Followed by undercoating.


Passenger side should have the bad stuff cut out, fabricate a patch from 22 gauge steel, Paint the area with two coats of POR15, fasten the patch to the body with structural adhesive and pop rivets. Paint the path with POR15 and top coat with enamel, followed by undercoating.


Just my two cents.
