Miq-I had spent fifteen years in body shops in heavy repair though we
always had a genius that sprayed the color for us, we sent it to him
ready for primer. I have sprayed and can paint when I truley have to
and do a reasonable job of it. Could you tell me, are your spraying
techniques much different with the different systems? Also what do you
think of the turbine system as one to try to eliminate the moisture in
the air lines that plauge us in this part of the country? How different
did that one spray from the old siphon type guns? Thanks
