Was wondering if any one here has used one of these small hand held sand blasters and had decent results. Saw one at Tractor Supply called a job smart, looks like a large paint gun. I used to have a good sand blaster and high cfm compressor but sold it all and understand the difference between a real blaster and one of these types but I just want to blast the dash I bought for my 47 ford. I have seen some others sorta like this with a different set up. A fellow I knew some time ago had a setup where you just poured sand or media in a a bucket and it was gravity fed and was crappy so I know the difference of a gravity vs pressurized blaster.
