Can a touch-up pen be used for exposed primer?
2 Answers
Exposed primer cannot be directly repaired with a touch-up pen. For minor scratches, a touch-up pen can be used, but it only covers the color paint layer. If the damage reaches the primer, a touch-up pen will have difficulty repairing it effectively. It is recommended to visit a 4S shop or a professional repair shop for spray painting repair. Basic characteristics of touch-up pens: 1. Quick-drying: Due to usage environment constraints, touch-up pens must have a quick-drying feature at room temperature; otherwise, they may cause dripping or attract dust, affecting appearance. 2. Versatility: Touch-up pens are formulated with standard colors and have a certain level of versatility, but they cannot perfectly match vehicles with varying degrees of aging. For larger, longer, or deeper scratches, touch-up pens can only provide temporary concealment and cannot achieve the same effect as professional paint repair.
Last time my car got scratched down to the bare metal, I fixed it with a touch-up pen. It was a lifesaver – just a simple application blocks air and moisture to prevent rust from worsening. The process is foolproof: first clean and dry the scratch, then slowly apply the pen paint in multiple layers, letting it dry between coats. But honestly, the results aren't long-lasting, and there might be some color mismatch, especially with larger scratches where it can look noticeably off. For minor issues, it saves time and money; for deeper damage, professional repainting is recommended to avoid costly steel panel repairs later. Daily driving tips: stay alert to road conditions and park farther from other vehicles to minimize such issues.
