I put the whole jar in mine, but I used 3" set up. Also, don't have air valve on/ open when you plug in air, open valve very, very slowly...adjust to what is needed to make paint fluidly, without the volcano effects...I have a different cup for each container, and store with a cap...
Proud to have served with and supported the Units I was in: 1st IDF, 9th INF, 558th USAAG (Greece), 7th Transportation Brigade, 6th MEDSOM (Korea), III Corp, 8th IDF, 3rd Armor Div.
