I am looking into going after larger mobile jobs. We have been in business for about 4.5 years and just are not quite where we thought we would be.We do most of our blasting in the shop. I am thinking about getting into blasting tanks and such. We currently have a Sullair 375cfm , IR 185cfm, 2 600lb pots,a Schmidt Accustrip 12sx pot, and a cube van. Any suggestions? Where is a good place to start?
