How to Find the Right Paint
Every auto parts store should have a booklet of car touch up paint colors on display. Simply look up your vehicle’s year and specifications. The list should have a variety of factory colors that were used on an automobile like yours. If it only has one designation for white, use that type on your white car.
You can also find the paint number on a plate on your car. The location differs according to make and model. To find it, consult the owner’s manual or call the dealer. The plate with the color number could be positioned on the driver’s door, by the windshield wiper mount under the hood, near the radiator or elsewhere.
Clean and Prep
Clean the area that you want to repair with soapy water, and dry it gently with a soft cloth. To temper rough edges, apply a bit of automotive polishing compound over the damaged paint surface. Stick to about a dozen swirls because too much chafing will cause damage. Follow up with a wipe of denatured alcohol on a soft cloth to remove any remaining dirt and wax.
Prime
Use the bottom end of a book match to apply a bit of primer. It should just fill the chip area and barely reach the ends of the undamaged paint that surrounds the flaw. Let it dry for a minimum of 30 minutes.
Paint
Once the primer has dried, apply a bit of paint. Let it dry for an hour, and add another coat. Leave the second coat alone for a few days to allow it to cure. After this waiting period, finish up with polishing compound. Simply rub it across the paint edges to smooth them down.
If you only have matching spray paint, put some of it into a small container and use an artist brush to apply it. Remember to not conduct paint repairs in direct sunlight or when the temperature is lower than 50 degrees.
