I'm thankful that this 92 D1 has very little rust, all things considered, but I noticed the pad under the rear carpet was wet after a recent rainstorm and saw some rust on the floor panel. I stripped everything out this morning to take a closer look. Most of the rust spots are surface but there are a couple places, especially the left rear, where it looks like water has sat for quite a while (this is where the pad was wet). 2 questions:
1. Recommendations for repair - should I cut out and replace the rustiest portions, or just grind, prime, and paint? The panel seems to be structurally sound for the most part.
2. Before I undertake any repairs, I need to locate and correct the leak. Any recs for where to look? I can't find any obvious points of entry. There is no rust or water stains that I can see anywhere above the floor but I don't see where water is getting in and under the carpet. Figured there may be a "usual suspect" that I can get clued into.
I also noticed a couple wires badly worn through on the fuel tank sending unit. The fuel gauge works but I'll repair those before I button everything back up. (fyi, that's Kroil on the fittings just to dress the rusty bits)
Thanks all!![IMG_4615.jpeg IMG_4615.jpeg](https://discoweb.org/data/attachments/57/57279-4e67790ff9667f4303bdf274c225bff8.jpg)
