I've got a 1976 Mercedes 300D that has advanced rot in the floor pan of the rear passenger seat. I thought it was a much smaller hole than it actually is, so I was visualizing a welded patch or even a JB-Weld-ed patch. We already don't allow anyone to sit in that seat so I'm not worried about someone putting their foot through the floor (a very real possibility as it is right now). What I'm looking for are ideas that'll seal the hole, a structural fix (so that someone could sit there) is not a requirement. After pulling up the rusted parts as much as I could today, I'm thinking this fix is outside the realm of my capabilities, especially since my new knee combined with my busted up old knee makes it difficult to kneel for any length of time, and i have no access to a lift to work on it from the underside. I don't know how much further the damage has gone, but I know I can poke a hole through the seam to the left of the Dremel with a paint scraper, but not the surrounding metal. Repairing this "properly" might cost more than the car is worth.
Here's what it looks like:
The light beige color is the floor carpeting sitting on the ground beneath the hole, with the Dremel there for a size comparison.
Anyone got any ideas on a "quick" (as in maybe an entire weekend's work) fix? Is anyone in the east King or south east Snohomish county willing to lend a hand to get this fixed? I don't expect you to work for free, we can negotiate compensation.
Rita's understandably hesitant to drive the Mercedes with a giant hole in the floor pan, I'd like to get this fixed.
