Just wanted to share my experiences. Bought a low cost sand blast pot a few weeks ago, now finally found the time to try it out properly (pot of the $300 price class, average) Had the great luck that a company was blasting on location nearby and that i could get all the old grid for free. (27000 kg!) That grid was rough, but became too fine for them to use, but for the purpose i need it for it´s just fine enough. First victim was a fan shroud, rusted up and crappy. I took the alternator off and blasted it. What a result, no rust at all anymore, unit looks great. Finished off with flat black heat resistant paint. Next victim, a large power box we want to use for another purpose. Same result, nice smooth finish, after painting it looked like new! Third victim, engine mounting bar. Same result as well. I think i´m addicted, i like the finish it gives.
