I saw an episode of Hot Rod Garage last night that had this thing called the Dustless Blaster. It's amazing, this guy blasted an impala in under an hour. It had body filler everywhere too. It might be simple but it blew my mind, I looked up there website www.dustlessblasting.com. They're actually fairly cheap investment wise. The one in the video was a little over $4000. But you would have to have a special air compressor as well I reckon. But I think it would be great side work and make what you paid for it ten fold. What do you guys think of it?
