Solutions for when the vehicle's primer is scratched off: 1. If the scratch is not very noticeable, it can be repaired by waxing; 2. If the scratch is deeper, it can be removed by polishing; 3. If there is a dent after the scratch, it is necessary to go to a repair shop for panel beating and repainting; 4. The primer can be simply patched up using a paint pen. The car primer is the first layer of paint applied to the car body, serving to protect the body. It directly contacts the body, which is mainly made of metal, requiring the primer to have good anti-corrosion and anti-rust properties, as well as excellent adhesion, including adhesion to the body and topcoat.
When I noticed the car paint was scratched down to the primer, I immediately wiped off the dust around the scratch with a damp cloth. A friend from the 4S shop once told me that exposed primer on metal parts can rust within two weeks, so it's crucial to address it promptly. For small scratches, I use a touch-up pen to cover them—like the 10-centimeter scratch on my car door last time, applying three layers of the touch-up pen worked quite well. If the damaged area is larger than a coin, it's better to go for professional repainting; nowadays, partial repainting at chain shops costs around 300 yuan. I always make a point to park away from bushes and stone posts, and I keep car wax and scratch repair paste in the trunk year-round to handle minor scratches myself.
