I had my frame, and all the other big metal parts sand blasted by a pro shop.
Tried doing it home style, and it just was an exercise in frustration only to not get what I was looking for.

No idea what options you have in your area, but in my case I stripped everything off the chassis. Kept the chassis as a roller for mobility, and all the other parts I wanted done I disassembled and put wire loops on everything. (Did that to save the shop time on my stuff, just to help shave man hours off my bill).

Got all my stuff back, and couldn't have been more happier with the results.
IIRC the cost wasn't prohibitive at all, as a matter of fact it was the best money I probably spent on my project.
