Repairing car paint chips generally have the same steps as repairing scratches on your vehicle. The amount of work you will do for a car paint repair will depend on how far the chip damaged your car.
Clean the damaged part on the car’s body thoroughly. This will help you determine how badly damaged the car is. Use soap and water to clean the area and wipe it off with a cloth. Make sure the area is dried out properly to prevent any moisture that may lead to rust.
Determine how bad the chip is. Check to see if the primer is still intact or if the chip has gone through the bare metal. This will determine the amount of touch up or repair you need to do. If the metal has been exposed and rust has already appeared, you need to sand the area.
Sand the chipped area to remove any rust. Only do this if rust has already appeared and the chip has reached the metal of the vehicle. Use the 600 grit wet/dry sandpaper to do this. Glue the sandpaper to the eraser end of a pencil. In this way, you will only sand the chipped part and not more than what you are suppose to.
You can also use the solvent or alcohol to remove any rust on the area. This will help to remove any sanding dust that may have gathered on the chipped area. Let this dry before doing anything to the frame.
With a toothpick, flick the paint edges of the chipped part to get rid of any loose paint. With a small amount of water, dampen the auto paint chips. Use another sandpaper or pencil to loosen up the chip and surrounding paint. This is to allow the paint you will apply to adhere to other parts of the vehicle’s frame.
Pour enough primer on a cup and use a toothpick as an applicator. Apply a thin layer of the primer on the area. Make sure that you allow at least two hours to dry the primer up before you proceed to the next step. Apply primer to all the chipped area only. The primer should only be applied below the surface of the intact paint, otherwise it will end up looking like a paint bump once you’re done. After you have primed all the areas, lightly wet-sand the area and wipe it off with alcohol.
When using touch up paint, make sure you follow the directions properly. For any other auto paint you will use for a car paint chip repair, only use a minimal amount. Using a different toothpick, dip the toothpick to the paint and apply it on the area. Do not use more paint than necessary. Allow the paint to flood the chipped area and let it dry for at least two hours. Repeat the painting process until the area is full of thin layers of paint. Allow the paint to cure before sanding.
Sand the area using 2,000 grit wet/dry sandpaper. Use a back-and-forth sanding motion until the new paint is almost the same level as the surrounding area. Clean the sanded area and put in a coat of wax and polish accordingly.
