•Surface Temperature (Actual surface temperature of the vehicle) between 50 (10oC) and 80 oF (26oC) products will work well within a much broader temperature range, i.e. 45° to 90° F (4.5-32oC) but at 45 degrees it will take much longer to dry, perhaps as much as two to three hours) but the best results will be achieved in the 60° to 70° F (15-21oC) range surrounding air temp (ambient or room) must be 55oF (12oC) + to ensure the minimum vehicle surface temperature of 50oF (10oC) which is recommended as a minimum by most car care product manufacturers.
Higher temperatures will cause the solvent oils in polishes / waxes to flash leaving no surface lubrication, which will lead to surface marring (hence the advice ‘do not use in direct sunlight’)
•Ambient Temperature (outside air or surrounding air temperature) (ambient or room) should be 55oF (12oC) + to ensure the minimum vehicle surface temperature of 50oF (10oC) which is recommended as a minimum by most car care product manufacturers
•Relative Humidity (Moisture content of the air)- RH 50% +/-10%
•Inside Air Temperature (Room Temperature) 70 – 75oF +/- 10oF (21-24oC +/- 12oC) and 50% relative humidity +/- 10%
•Air movement or windy conditions will increase the evaporation rate but potentially make some products more difficult work with, especially sprayed products. Perversely this can lessen wax / sealant drying time.
•Product Temperature- 40 – 50oF (8 - 10oC) is a good product temperature working range
•Swipe Test after sufficient drying times do a quick swipe test with your finger, if no smearing or drag is evident; the residue is ready to be removed.
