I am not a PPG fan or user but somewhere it will say on the can how much reducer to use or it will say ready to spray but I dought it as I have only seen that on some primers and or sealers. Years ago I worked for a guy that used PPg and if I remember correctly it was 1 to 1 but I don't remeber what line it was just that he used allot of single stage. If not call the paint counter at the parts store where you bought it, they will know.
