Re-spraying is a great way to restore a vehicle's appearance. The process will virtually eliminate signs of minor dents, scratches and other imperfections. Before re-spraying, however, it's important to properly prepare the vehicle in order to achieve desired results. Proper prep will also ensure only the targeted areas of the vehicle are re-sprayed.
Move the car to a warm and dry area that offers ideal re-spraying conditions.
Rub the surface of the vehicle with 80-grit aluminum oxide abrasive paper until you reach the metal.
Tape newspaper over any areas of the vehicle that are not going to be re-sprayed. Use masking tape to secure the newspaper. This type of adhesive will not damage the existing paint job.
Spray on several coats of primer to the clean, dry area that you plan to re-spray. Wait 15 minutes between each coat and let it dry overnight for at least 24 hours.
Use 1500-grit wet and dry paper to sand down the primer. Continue sanding until it feels smooth.
