I'm curious about the FLG-5. I see all kinds of reference to it in Europe and Australia, but is it not available in the USA? Perhaps under a different name?

I found it by watching the youtube channel "The Gunman" He says he loves it almost as much as his Tekna.

The FLG5 is the EU version of the SGK gun made in South America. It actually came out before the FLG4 made in the US.
Given that it's a more recent spray gun with newer technology made for a more discriminating (U.S.) market, the FLG4 likely has better performance and atomization than the SGK/FLG5.

I saw the same review by Gunman. One question I have is: it states that its for solvent base not water base, whats the difference?

Well I bought the gun on ebay last night, I mostly use Pro Spray out here in CA which is mostly likely water base...? I can use it for cc only but is there any reason not to use it for bc for my application?

Im back haha. Well I received the gun pretty fast, all the way from England. Its a nice gun but unfortunately I cleaned the gun and found it to be leaking air out of the air cap once put air thru it. It doesn't leak fluid just air, this isn't normal right? Hopefully I can get this figured out so I can get some use of her.
