If it were a hemi I might replace the whole pan. I saw a left front section for $199 on the AMD website. I thought I might order that, have a pro weld it, and clean up the rest of the Entire pan, hit it with wire brush and rust remover, then coat with white rustoleum primer before installing the carpet. Should that protect adequately if done right?
Also, should I rust proof the bottom of the patch before dropping it off for welding? I can't get under the car at home.
