A FOLLOW UP, NOW THAT I'M A FEW MILES IN:

Today, I painted a long, second story deck railing run. It was the third run I'd done with this new investment. I was using Sherwin Williams Emerald. A tough cookie for my four stage. Even a five stage, I'd bet. It shows up on several of cites dedicated to addition of the cup, as a problem child for its thickness.

Up to this point, the system labored to move the paint through the 7' fluid supply hose and didn't lay down as much as I could like.

ON A WHIM:

(1) I took the whip air hose off and went straight to the gun, as with the stock set up, bypassing the air to and through the remote pot completely, as if I was running the stock cup under it.

(2) Too, I grabbed my pancake compressor and a flex hose.

(3) I pulled the connector into which the check valve attached, to pressurize the gun off the pot.

(4) The hose fitting fit the hole the HVLP pressure hose attached to perfectly.

(5) I fired up the pancake and set it for about 15-20 pounds, to push the paint through the 7' hose much harder than the 10 pounds of the gun would push (I can go up to 50 pounds).

(6) I fired up the HVLP with the air pressurizing the pot and started spraying.

SIDE NOTES:

(1) NO LONGER is thinning necessary, and I get good coverage. I am very happy with the results.

(2) The highly flexible air supply hose connects only to the remote pot, so throwing the gun around is still no big deal. Even moving the pressure pot seems no more complicated that it was before.
