Here is a step by step guide for applying car protectant spray to your car:

1. Start by washing and drying your car thoroughly to remove any dirt, grime, or debris. This will help the protectant spray to adhere properly to the surface of your car.

2. Once your car is clean and dry, shake the bottle of protectant spray well to ensure that the ingredients are mixed properly.

3. Hold the spray bottle about 6-8 inches away from the surface of your car, and apply a thin, even coat of the protectant spray. Be sure to cover the entire surface of your car, including hard-to-reach areas like under the hood and behind the wheels.

4. After you have applied the protectant spray, allow it to dry for a few minutes. This will give the protectant time to penetrate and bond with the surface of your car.

5. Once the protectant has dried, use a clean, soft cloth to buff the surface of your car. This will help to remove any excess protectant and give your car a shiny, polished finish.

6. Repeat the process on the other areas of your car, including the windows, headlights, and mirrors.

7. Once you have applied protectant to the entire surface of your car, allow it to dry completely before driving or exposing it to the elements. This will help the protectant to fully bond with the surface of your car and provide maximum protection.

8. Be sure to store your protectant spray in a cool, dry place, and follow the manufacturer's instructions for proper use and disposal.
