Wet sandblasting my brush hog with a 28.00 Amazon wet sandblaster. Wet sandblaster well worth the money. Will paint Kubota orange. Next project is to wet sandblast the smoker firebox surface rust on 3/8 " thick sheet iron and paint.

set sand in a bucket in back of truck, if sand gets wet it will clog the tube.

10 minutes of blasting left side only, and one 50 lb bag of sand. I figure 9 bags total 45.00 and an hour and a half labor.

Sand all over trailer and on 3300psi washer about 25 feet away.

Why the wet sandblaster instead of the usual dry sandblasting? What are the benefits of the wet over the dry? I use the dry with good results and can recycle some of the sand.

Can you explain how this works? Never heard of wet sandblasting.

I believe you are using a pressure washer that siphons the sand out of the bucket, the water keeps the temperature down on the metal, if I understand it correctly so less warp-age on thin sheet metal, plus you are not creating a dust storm.

My Pressure washer adds 3,300 PSI to the mix, a lot more than air.
Go to youtube "wet sandblasting"
For me I will never go back to grinding, air sandblasting, or chemicals. Less time, less work.

I have never been around a wet-blaster. It seams like the metal would start rusting as it dries. Is this possible, or am I way off base here?

EXACTLY and why I never do that, always dry and always Black Diamond.

You wet sandblast and surface rust immediately starts forming. Not something I'm interested in one bit.

I'm doing a brush hog and there is no rust.
