Floorpan Rust
I'd knock all the floor plugs out...
What's the point, just sweep the debris through the existing holes. :toothy7:
Are you planning to drive this car while you are waiting to fix the rust problem? If not, and you just want to stop further rusting, buy some rust converter. Wire wheel the major rust off, clean up the mess, and give it a good dose of converter. It will convert the ferric oxide into a gray or black iron phosphate.
If you want to temporarily fix the holes and reinforce the floor a bit until the final repair, you might consider using some "kitty hair" fiberglass to lay down a layer after a good de-rusting like described above.
