How Long Does It Take for Rust to Form After the Primer Is Exposed?
1 Answers
The exposed primer of a car will start to rust in about one and a half months if it rains; if it doesn't rain, rust will form within approximately 3-5 months. Below is more information about primer repair: 1. Minor scratches: If there are minor scratches, polishing can be used to restore the shine of the paint. Use a polishing wheel with a polishing oxidizer to remove debris and oxidation layers attached to the paint, smoothing out the fine scratches. The chemical will penetrate the paint, causing a restorative change, achieving a bright and new effect. 2. Deeper scratches: For deeper scratches, first check if the metal surface is exposed. If the metal surface is not visible, rust will not form, and you can carefully apply touch-up paint, dabbing it on with a brush tip, then waiting for the paint to dry completely. 3. Deep and thin scratches: For deep and elongated scratches, colored putty can be used for effective repair. Use sandpaper on the scratched area, avoiding unnecessary expansion of the damaged surface, and focus on cleaning the dirt thoroughly. Apply the putty carefully to ensure it fully penetrates the interior, then apply a compound and wax. 4. Scratches exposing the primer: If the scratches on the car body have exposed the primer, it is advisable to visit a scratch repair shop as soon as possible to prevent rusting and corrosion of the surrounding paint.
