The only thing you could possibly damage is the sheet metal, if that is true it is more about how close hold the wand and how much pressure you use. You aren't going to damage cast or forged etc. I doubt if either is more aggressive than sand. I usually go over my parts with a wire wheel, partly to get rid of any imbedded sand and partly to make it smoother, I really doubt if the "smoother" is necessary. No matter what you do the 170 coverage will be the same. That said, I usually use sand for the big parts outside, and have just recently used a black beauty clone in my cabinet blaster--I don't have a clue what the grit is. [Reply]   [No Email]
