Hi Greg, Certainly an option to try and get the effect!
As for the problem you have...you may or may not know, but the water in the line sounds like condensation buildup in the compressor. If you are using a compressor with a tank, try opening the valve on the tank and allow the built up water to come out. If you are using a tankless compressor, the condensation can happen from environmental condition or continued use whereas you have been painting straight out. There are some water trap regulators available fairly cheap. This will collect most of the water and allow you to set it free while during a long painting session. If environmental...a dehumidifier can help this or moving your painting area to a dryer location. Also, damp and/or rainy days can wreak havoc and even a dehumidifier will have trouble keeping up.
