When you are waxing your car, park your car in a cool, shady spot. This is important so wax does not get baked on your car in the sun. If you do not have access to park in a cool, shady spot like a garage, then I recommend extra caution. Wax only one part of your car at a time to avoid car wax being caked on. You do not want the sun to bake the wax onto your car. Avoid waxing your car if it is too hot or too cold. Both of these can interfere with your waxing process.
