Once the damaged area is clean and you’ve chosen the right paint chip repair kit for your needs, the next thing you should do is remove any rust. To do this, dab a Q-Tip with WD-40, swab it against the rusted area, and repeat the process until the Q-Tip returns clean. If you find that the rust is deep enough to damage your car’s body, you may want to consider getting a professional opinion before proceeding because it may require some additional sanding.
After all the rust is gone, the next step is to apply automotive primer using the applicator brush that came with it. During this process, wait for the primer to dry completely before attempting anything else. Next, apply the touch-up paint in the form of a pen, spray, or brush.
To avoid unwanted bubbling or streaking, let the paint settle properly before adding another layer. To match the new paint with the rest of your vehicle, you may also have to polish and buff the rest of the car using a power buffer.
Once you’re happy with the appearance, allow the paint to dry completely before checking if it will need another coat. Lastly, to add a new layer of protection from the elements, you can use wax, an essential car cleaning tool you probably have in your garage.
