Re: 1950 2395 Floor Pans

Floor and trunk pans arrived today from C2C. BDeB was correct, it looks like either their stamping machice lacked strength or their dies weren't deep enough. I am debating using them as is, restamping depressions individually, or welding small round and square deeper depressions to replace C2C's. Probably the "path of least resistance. It will be next week.

I am sandblasting the exterior rust and priming with metal etching primer, which will take me to Sunday to finish.

Then I will lay in the floorpanels and mark what they will cover. Once removed again I usually mark one inch in from the floor markings and cut off the excess with a cut off tool. Then comes the messy part, the sandblasting to expose decent metal. Once the sandblasting of remnant floor and crossbraces is finished, I again mark and cut back any weak or thin areas. Sandblast again and start to reconstruct. First patch pieces to bring the perimeter lips even one inch under the floor pans. Then I drill the perimeters of the floorpans with 3/8" holes every 3" and flange the one inch overlap so everything ends up flush with no ridge or seam. The holes will allow me to spotweld. I will again assemble the floorpans and recheck fit and support. If everything is good I will then spray the sandblasted crossbraces and structures that will not be welded with bed liner from the top ( hard to reach when the floor is welded in) and let it set. I will wash the floorpans with either Muriatic Acid in a dilute solution or with vinegar. Then wipe them down with acetone. Place wet rags on the crossbraces but not so thick as they cannot be removed when finished welding. It is now ready to weld. I use a spot setting on my MIG and adjust until there is no burn through but good adhesion and penetration. I cross tack to prevent flexing and warping, going from left to right and top to bottom in rotation. Checking to make sure everything is still right I finish welding and wire brush. I always finish my floors, inner fenders, trunks, etc. with bedliner (bulletproof) and my frame and suspension in Semi Gloss Black Rust inhibiting paint
