Is repainting necessary if the primer is exposed?
2 Answers
If the metal is visible, repainting is required. If it's white, you can get some white paint from a paint shop to dab on, or use a touch-up pen. Definition of car painting: Car painting refers to applying a layer of paint to the car's surface to protect it. Automotive paint is usually baking enamel. In car manufacturing plants, after the frame and body are welded, the next step is painting. Types include standard paint, metallic paint, and pearl paint. The car painting process involves applying putty, sanding, and painting. Precautions for touch-up painting: When repairing the car's paint surface, always go to a professional institution and ensure the repair is done by a specialist.
Last time my car got scratched down to the bare metal, my neighbor who's an experienced auto repair technician told me I must address it promptly. Exposed primer on metal body panels means losing the protective layer - rainwater can cause the steel to rust through in just two or three months. Plastic bumpers fare better, but metal areas like doors and fenders absolutely require repainting. I've personally seen the tragic sight of a roadside car with rust holes in its rear wheel arches. Proper repainting involves multiple steps: first sanding smooth, then applying rust-proof primer, followed by basecoat and finally clear coat. A temporary touch-up pen can hide the damage, but for a permanent solution, professional repainting is necessary.
