wet sandblasting

Anyone tried this procedure? It is an attachment for your power washer. A seperate e wand 1 section picks up the sand and guides it towards the tip ,then mixes with water and propels out to clean what ever you need blasted

I've never tried the newer wet blast stuff, but used to work on Arm and Hammer Soda blast equipment years ago. It worked absolutely outstanding wet. From what I see, these newer wet blast systems, are using like crushed garnet, or some other relatively inexpensive media, and work on nearly the exact same principle. What exactly are you trying to blast? Often times, you can dry blast with a different media, if blasting would typically have an undesirable effect. (Panel warpage....etc.)
