The question may seem so simple that it's silly, but it's a sign of my ignorance on the subject...
I have a Fuji Q4 HVLP system and some plastic liners for the fluid cup on the gun. In theory, you put this in the cup and put the finish in it so simplify cleanup. However, I've yet to do it ... probably because I'm not sure about how this really works and if it would mess up the gun. The cup is pressurized, I believe, and as the liquid is drawn out won't the plastic liner "suffocate" the system?
Am I missing something? Is this of no concern? Should I use the liners?
