anyone know of a good rust fighting agent that i could pick up at NAPA for fairly cheap. Im patching the floorboards tomorow so i just thought i would spray somethin down that might help on the rust a lil bit in the future

 

You mean the floorpans underneath the carpet? I just sprayed Rust-Oleum Auto Primer on my floorpans, and I have no rust at all. Granted, the car's been garaged, but I sanded them down and sprayed them about 8 months ago and none of it has come back yet. Sorry if I misinterpreted what you're asking.

 

A good primer/sealer is all you need. If you just want to grab something from your local auto parts store then Rustoleum works pretty well. I think Duplicolor has one too that's pretty good.

 

POR-15, nothing better!! POR15

 

yea, the pans underneath the carpet. also how important is it to cut out all the old rot and rust. and has anyone ever heard of putting a lil bit of tar down below the patch.

 

i used Rust Bullet on the underside of every inch of my car. this stuff is practically bullet proof. it's the same principle as por15
