As someone who just did some sandblasting on my T parts, may I offer a suggestion? Take it to a pro sandblaster and let them do it. I probably ended up spending just as much with the paper suit, goggles, face shield, mask, sand, electric, etc, and had a few hundred pounds of sand to clean up when I was done. It went everywhere in a 100 foot radius. Next time I am hauling it to someone else to do.

It might not be a bad idea to rent a 4000 pound pressure washer to get the grease and grime off, because that will save you some money and time at the sandblasters. We had a 4000 pound unit at the marina, and it would remove paint !
