It is necessary to install window rain deflectors on a car. Here are the steps for installing rearview mirror rain deflectors: 1. First, clean the area where the rearview mirror rain deflector will be installed to ensure there are no debris that might prevent proper adhesion. 2. Then, compare the position of the rain deflector with the rearview mirror to check if the size is correct. 3. Once confirmed, peel off the 3M adhesive backing on the rain deflector and attach it carefully, ensuring there are no air bubbles. 4. Finally, press the rain deflector firmly back and forth with your hand to ensure it is securely fixed. You can also use a hairdryer to heat the adhesive for better bonding strength.
