How to Repair Scratches on the Rearview Mirror Plastic Shell?

Use a compound to treat the scratches by wiping in straight lines, then apply wax. Start with coarse wax followed by fine wax, moving in the same direction from the inside out to remove minor scratches. Before using a touch-up pen, shake the paint inside thoroughly. Apply the base coat like nail polish, and you can add a certain amount of thinner to the touch-up pen to ensure smooth spraying. First, wash and dry the car. Apply rust remover to the scratched area, wait for 10-15 minutes, then wipe off the rust remover with a tissue to prevent further rusting in the scratched area.
Scratches on the plastic shell of the rearview mirror are really annoying. I’ve driven several cars myself and often encountered this issue. The most reliable method is to first clean the scratched area, using a damp cloth to remove dirt and dust, ensuring the surface is clean and dry. For minor scratches, you can try using toothpaste—apply a small amount to a soft cloth and rub it repeatedly along the direction of the scratch for a few minutes, then wipe it off with a damp cloth. This often works well, is cost-effective and convenient, and also helps prevent corrosion. For moderate scratches, you might need wet sanding with 1500-grit sandpaper to gently smooth the surface, followed by applying plastic polishing compound and buffing it in circular motions. For severe scratches, it’s best not to bother—opt for professional repair or buy a new shell replacement to avoid compromising the plastic’s strength and appearance. When parking, be mindful of obstacles and regularly apply automotive plastic conditioner to significantly reduce new scratches. The entire process requires patience—take it step by step without rushing to ensure the rearview mirror remains safe and reliable, avoiding any hazards while driving.
