1. Clean and Sand the surface thoroughly
Before refinishing, clean the vehicle body thoroughly with a degreaser to remove oil and contaminants. Sand the damaged area with 400#–600# grit sandpaper to improve paint adhesion.
2. Select appropriate Primer and ensuring complete drying
Choose a primer compatible with the substrate, for example, use epoxy primer for metal surfaces and plastic primer for plastic components. After primer application, allow it to fully dry before applying the topcoat.
3. Control auto paint products mixing ratios
Mix hardener and thinner strictly according to the manufacturer’s recommended ratios, and use the mixture within the specified timeframe to ensure complete chemical reaction and optimal adhesion.
4. Optimize Application Environment
Maintain a stable temperature and dust-free environment during application to improve coating quality and adhesion.
