How to Install Rearview Mirror Rain Guards?
2 Answers
Clean the inner side of the car's rearview mirror with a damp towel and let it dry. After confirming the direction of the left and right rain guards, pre-install them on the rearview mirror to check the effect. Once the position is confirmed, peel off the covering of the 3M double-sided tape. To maximize the adhesive effect, you can use a lighter or a hairdryer to heat the adhesive surface back and forth to increase its activity. Align the rain guard to the position, gently attach it, and press firmly with your hand to ensure a complete fit.
As someone who frequently works on my own car, I've accumulated some insights through multiple installations of rearview mirror rain deflectors. First, always choose a sunny day for the operation, as lower humidity ensures better adhesive performance. Cleaning the mirror surface is crucial—use alcohol wipes to thoroughly remove any dust or grease, otherwise the deflector may easily come off. Proper alignment is key; roughly position it first without rushing to remove the adhesive backing. After slowly peeling off the backing, start pressing gently from one end, smoothing from the center outward to avoid air bubbles. Apply even pressure for about a minute, then let it sit for half an hour to fully bond. Through several attempts, I've found that patience prevents future loosening. Once installed, driving in the rain becomes much easier with significantly improved visibility. Regularly check the adhesion, as summer heat may soften the glue—avoid frequent wiping. Overall, it's a small task with noticeable results, saving trips to the repair shop.
