What type of sand are you using? I used to be able to get no 1 white sand but they told me can't get it anymore. Play sand from Home Depot/Lowes won't work in my pressure blaster. I just love sandblasting myself. It's so much fun!
It's just a #4 silica sand I get at the local Peavy Mart - similar to Harbour Freight I believe. I think the play sand is a little coarse for a cheapy little blaster like mine. #5 is about as coarse as I can go and still get decent results.
