There will be no impact after reattaching the fallen plastic cover of the rearview mirror. How to repair scratches on the rearview mirror: Use a compound to treat the scratches, wipe in straight lines, and 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 use, shake the paint in the touch-up pen well, apply the primer like nail polish, and you can add a certain amount of thinner to the touch-up pen to ensure smooth spraying. The purpose of using rust remover first: First, wash and dry the car, apply rust remover to the scratched area, wait 10~15 minutes, then wipe off the rust remover with a tissue to prevent the scratched area from continuing to rust.
Last time I backed up, I scraped off the side mirror casing and tried to force it back in—turns out there's a real technique to it. If the drainage groove underneath the shell isn't aligned properly, rainwater will accumulate behind the mirror, and in winter, the freezing water can directly damage the adjustment motor. The clips are the most problematic—I only felt at ease when I heard the 'click' sound during installation. Otherwise, at high speeds, wind would whistle through gaps, rendering the soundproofing foam useless. Modified mirrors require extra attention—those with blind-spot monitoring have millimeter-wave radar inside the casing. If it's misaligned by even two millimeters, it's like having bubbles under a phone screen protector, causing false alarms. After washing the car, remember to check the seams for trapped dirt, as it can eventually lead to cracks.
When installing rearview mirror covers yourself, pay special attention to the sealing. I learned this the hard way. Last time after installation, I noticed severe vibration at highway speeds. A mechanic found three broken clips. The technician said plastic covers with insufficient rigidity can cause airflow resonance above 80 km/h. Also be careful with turn signal wiring - a fellow car enthusiast pinched flexible wires during installation, causing a short circuit that blew a fuse two weeks later. Now I inspect cover seams during every car wash, applying silicone strips to any gaps over 1mm to prevent rainwater seepage that could corrode the motor and cost thousands in repairs.
