use SLOW drying reducer,,
Oh and drain the tank on your compressor,, keep the airline off the floor while your spraying,, and drain the airline too before you spray.
did I mention to drain the tank on the compressor?
ask me how I know,, one body shop I worked at installed a 500 gallon air tank for that specific reason, to let the air cool and condense,, worked great,, until we forgot one month to drain the tank, there was like 5 gallons of moisture in there! yechhhh,,
