I do a few rehab projects with grandsons each year...mostly decks, seat pans, few footrests, an occasional plow blade, etc.....some need more rust cleaning than others..if not very severe rust or pitting, then grinder, wire wheel, scaler etc often get job done. However, I did do some consideration couple years ago to buy blaster....Instead, I use a nearby fairly priced professional sand blaster who has done various projects for me... Every one of us has different considerations, but for me I'd rather have him deal with all the downside issues of doing the blasting than me. .... I'm happy dropping project with him and picking it up few days later. No $ cost for me to buy and maintain equipment, buy media, no mess, no labor, no sweating, no clean up, no health considerations, etc....and great perfectly finished beautiful bare metal piece
