I used the blaster with no sand to blow it off. I use a diesel 100cfm compressor that blows a lot of air when I sand blast. Then blew it off again with shop air. Then paint it.


This is a surface that was pressured washed clean of all grease and oil before I sand blasted. You always want to remove that first. Because there's nothing worse than blasting grease and oil into the pores of bare metal and then try to get it grease free, almost impossible. And after sand blasting it's pretty rough and even a DA sander is not going to get to the bottom of the metal because it's textured after blasting. Perfect for paint adhesion.
