I'm a newbie looking to do some gun refinishing & small projects at home. In shopping for an air compressor & blasting cabinet I realized I don't know what I need to look for in minimum requirements of these devices. I will be working on both long guns & pistols. The compressor's size, power, & output appear to be important. And I hope to get some help selecting a blasting cabinet that's adequate for a reasonable cost. I'm not interested in cutting corners & will pay for quality.
