we got a home brew sand blaster and it just laughed at our compressor, apparantly you need a proper big compressor like the ones road workers use to supply enough air. You can rent them all together but some how I just cant see its worth while. It was someone local brett used, very local if im not mistaken (Fryston area), hes on nights at the moment so I'll ask him later today. They did do a nice job, I just hope it lasts. Wasnt expensive either. I'll let you know.
