You need a decent pressure washer, a couple hundred pounds dry sand, and a cheap abrasive wet blaster from Amazon (about 30 bucks). Way faster than dry blasting!
I forgot to add that it goes through sand fast. To do a whole car would likely take over 2000 lbs of sand depending on type of paint and rust.
Also if it stops shooting sand it likely got some water in the sand feed tube and clogged it with now wet sand, easy fix, just pull off the feed tube and blow out the clogged sand, make sure its dry, reconnect and it’ll keep working! This only happens if you stop blasting and leave it for several minutes and water leaks down the hose.
Happy blasting!
