Has anybody used one of the Dustless blasting units , they look great on the video's . http://dustlessblasting.com/automotive/ Here's a link where they used one on my Classic Car . I was interested in the small cheapest one for my house garage , a DB150 . The price isn't on the site , so I sent an email . $4995. U.S. At that price I'd have to sell my project to buy one , but if I sell my project , I don't need the blaster . I have an old upright sand blasting tank just sitting around with no place to go , so I'm just wondering what I would have to do to convert it over . I bet the parts won't cost me 5 grand . Anybody have any idea's what I'd need to do to convert my tank .
