i have a PRECISION AIRBRUSH AB-182. I am using revell Hobby air 700ml propellant. I was using a mix of tamiya olive drab/ Games Workshop camo green thinned with tamiya acrylic thinners.

I was airbrushing today, and i got bursts of a clear colorless liquid. It does not evaporate, and seems to be lifting the paint off the model. It does not dissolve in water, and repels even soapy water.
I suspect that revell put lubricant in the cans and my can has waaay to much. Other option is that games workshop paints dont mix with tamiya thinner and the clear liquid is some part of the paint; but the paint in the reservoir looks ok, no obvious separation.

Typically, it happened on the fuselage of my panda air cav huey (not exactly the easiest kit to replace). And if i cant fix it, the kit is practically ruined.

Does anyone know (a) what this liquid is? and More importantly (b) how can I get it off or cover it up.

Many thanks for any advice at all. (other than to get a compressor :-) )
