I just bought a Sammy and it's got alot of surface rust on most of the underside. I want to clean it up so it both looks nice and lasts longer. I'll be removing the axles, springs, etc. anyway, in preparation for a SPOA lift. I'll be doing the work in the back yard. Are sandblasters as messy as I assume they are? I've never used one... don't even know if they make portable ones that I could rent/buy.
What's the best way to remove the rust?
