You can still restore the rest of the car if there are damaged spots. Those damaged spots will just still look faded when you’re done. If the clear coat is gone, don’t panic! You can still sand and re-paint these spots, or the whole car if you have to. [2] X Expert Source Angel RicardoAuto Technician Expert Interview. 1 October 2019.

Try to make sure the car’s surface is at least 50 °F (10 °C) so the polish and wax don’t solidify. [4] X Research source

A power washer makes this job a lot easier, but a plan garden hose or bucket of water will do the trick too. Don’t try to wax or polish the car without washing it first. If there’s any dirt on the car, the brushes will scratch the paint.

Don’t start compounding or polishing until the car is totally dry. The compound won’t work right if the car is wet.

Clay bars are sold at any auto parts store. If your car only has minor sun damage, the clay bar treatment might actually fix it right up without further polishing. [8] X Research source

Car compound is a common item that you can find in any auto store. It works like sandpaper and removes damaged paint layers. You can do all of this by hand, or with a rotary buffer. If you use a buffer, make sure to press lightly so you don’t take off any of the car’s paint. [11] X Research source

You might need to switch to a fresh towel if the one you’re using gets too gunked up.

Car polish is also very easy to find at any auto store. It’s similar to the compound, but is less abrasive for a finer finish. Use a fresh pad to apply the polish! Don’t use the same one you used for the compound.

If some spots still look faded, then the clear coat was probably too sun-damaged. You can fix that by re-painting those spots.

If you’re waxing near trim or plastic parts of your car, cover them with masking tape first. The wax could discolor these sections. [16] X Research source

If you don’t have a shady spot to park, you could also protect the car with a sheet or car covering.

Washing and waxing the car yourself might be too time-consuming, so you can always bring it to a carwash for more convenience.
