Had a buddy soda blast my old unit before paint, my old one i sold. Looked like virgin metal when he was done. Of course dont know what that would cost if you had to pay for it. My buddy did it as a return favor.
Soda Blasting? Thats a new one on me unless you talking about Mentos and 7up. I'm going to look into have it doneby a commercial blaster, it's too much for my little el-cheapo Harbor Freight unit. Re-bar for the fire grate? I hadn't thought of that one, good call! Cheap to weld up too!
