Rear cab rot repair #1

The cab and all were dustless blasted, and sprayed down with phosphoric acid, a passivating agent. Any panels so treated will remain rust-free for years if stored inside.

The frame was blasted, epoxy primed, and polyurethane topcoated.

 The rot at the rear of the cab has been cut away in preparation for welding in a strip of 17ga metal. This inner rot must be repaired before the stamped exterior patch panel is welded in. The sheet metal in this area forms a square tubing running the width of the cab and offers strength to the rear of the cab. Classic Enterprises makes the inner and outer cab corners as well as the lower middle panel. Their panels fit very well. The outside cab corners have already been repaired.

The left hand pinch weld radius has been repaired, and we are now ready for the stamped center patch panel. We used to use weld-thru primer to back-prime pieces to be welded in. However, those cans/nozzles clog way too easily. A body shop buddy told me he is now using UPOL Acid Etch #8, so we switched. That is the grey color seen on that long strip. My nephew is way better at exterior patch panels than I, so he is the one to attack the CE stamped panel.
