Got the floors in and welded. Patched a small hole in the trunk floor right above the bumper mount, thats the only rust in the trunk area. A little grinding and seam sealer and I can start prep on interior for paint. Reinforced the rear cross member, it was rusted pretty thin around bumper mounts. Used 1/16th" steel plate, didn't want to go too thick 'cause that might pull the bumper out away from the body.
Took a break from welding and started sanding on the left rear quarter panel for about an hour.
I'm gonna try to get it sanded ironed out and into primer by thanksgiving.
