It is also best for your car to be in a covered area. A garage is the ideal spot to wax your car, but you should at least have some type of shade. You will want protection from the sun’s rays, as they can dry out the wax too quickly or too much. If access to cover is just not happening, you should at least wait until morning or evening, when it is cooler and less sunny.
You will also want a smooth surface for waxing your car. If there are scratches, rough spots or dull areas on your vehicle, it may be good to pre-treat those areas with a polishing compound first. This may look scary at first, as it can remove a fine layer of the clear top coat, but it actually improves the look of damaged spots.
