How to Determine if a Vehicle's Primer is Exposed?

[ColinRose]

Methods to determine if a vehicle's primer is exposed: The owner can gently touch the scratch with their fingers. If they can feel obvious unevenness or roughness, it indicates that the vehicle's primer is exposed. If the scratch is not very noticeable and the primer is not exposed, using a polishing wheel along with a polishing enhancer can remove the oxidation layer attached to the car's surface, smooth out minor scratches, and allow the chemical to penetrate the paint for restoration effects, thereby removing light scratches and refreshing the paint surface. If the scratch on the car body has already exposed the primer, localized touch-up painting is required. For large-area touch-ups, the entire original factory paint on the door must be sanded off before repainting. Owners can visit a touch-up center that offers quick scratch repair services for such touch-ups.
