Damage to sheet metal is NOT Ill repeat NOT related to heat. So if your potential hydro blaster is touting his services will prevent damage, run cause the guy is a fool or a liar.

Warpage is caused by the media acting like thousands upon thousands of little hammers penning the metal stretching it out as they hit the surface. You can take a themo heat gun and the measure the before and after blasting temps can you won't see a darn bit of difference in metal temp. How do you warp metal via heat if the metal never changes temp???

It wasn't heat I was worried about, really just looking for input if people have tried the process with success, I'm more or less talking about the small hydro blasting kit that can be used at home, if it work ok, I know its alot of work and will take a lot of time but I like the idea of dustless blasting, and there no one in my local area media blasting

Make sure to clean out EVERY last square inch while its still wet with a pressure washer. Wet media packs tightly and doesn't come out easily once it's dried. I'd rather use a traditional method as the water/media mix carries more momentum than dry media, so the warping could potentially be much worse.
