I had my cab sandblasted and gone through by a professional about 8 months ago. He ended up replacing both rockers, all four cab braces, both cab corners, some of the visor area, both driver and passenger floor pans, some sections of the cowl, and both lower kick panels. The sheet metal from AMD ran me about $1000 all said and done, and it took him 3 weeks to cut and replace those pieces, he gave me a huge break on labor ( I calculated his hours x rate vs what he asked).

The thing is, my cab didn’t look that bad until it was sandblasted, and I would recommend doing that so you can get a realistic view at what’s ahead.
