After waxing your car take cold water and apply over your wax. Spray a light mist of cold water over your waxed finish and wipe dry. This will help it cure faster. What I do is place a spray bottle 1/2 full in frezzer. Let it freeze. When you are ready to use run hot water in spray bottle. You want the coldest water you can get. Do not put the spray trigger in frezzer.
