The Bob Long Insight NG is unsurpassed in efficiency and speed for spool valves. It's not even close. The anodizing on this gun is simply amazing. It has a beautiful dust blue base, with GLOSS silver splash. How do they mix the gloss and dust? We're not sure, but I think there may be some strange Voodoo or Alechemy involved. However it's done, it's stunning, and so difficult that not many other companies even attempt it. Stand out from the crowd!
