To wax a car properly, follow these steps:

1. Wash the car thoroughly with car wash soap to remove dirt and old wax, then dry it completely.
2. Inspect the paint and use a clay bar or scratch remover if needed to smooth the surface.
3. Apply a small amount of wax onto an applicator pad or microfiber cloth.
4. Work in small sections, applying the wax in circular motions with light pressure.
5. Let the wax dry to a haze for about 5-10 minutes.
6. Buff off the wax with a clean, dry microfiber towel using gentle circular motions.
7. Repeat section by section until the whole car is done.
8. Finally, check for any leftover wax residue and remove it for a glossy finish.

Additional tips include waxing in the shade to avoid heat from the sun affecting the wax, and using quality wax products like carnauba or ceramic wax for better protection. Waxing every few months helps maintain the paint’s shine and protection.
