I forgot to post some of these photos of my interior progress last fall. I worked hard at sanding down a lot of the old adhesive (from the carpet), paint, and rust that was in the tub. There wasn't really any horribly bad sheet metal actually. The worst part was on the driver side, and it was just pitted. I ended up deciding not to cut it out simply because it still seemed pretty solid. Just patched the holes that I could by welding in small cutout patches and doing plug welds, and then I covered over a bunch of it with body filler to fill in the gaps left by other small pinholes and missing sections of metal. Anyway, here's some shots of my progress at cleaning up the tub when I was halfway done before any primer was applied.
