What is the installation method for car rain deflectors?

Installation method for car rain deflectors: 1. Clean the area where the rearview mirror rain deflector needs to be installed to ensure there are no debris that might prevent proper adhesion; 2. 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; 4. Press the rain deflector back and forth with your hand to ensure it is firmly fixed. Alternatively, you can use a hairdryer to heat the adhesive for better bonding. The technical name for rain deflectors is 'sun and rain guards,' and their function is to allow the car window to be rolled down to a certain height during rainy days without letting rainwater drip inside.
I think installing car rain deflectors by yourself is quite simple. The main steps are: first clean the edges of the car window glass thoroughly, especially removing any grease or dust, otherwise the adhesive won't stick properly. Then wipe it completely with alcohol pads and let it air dry naturally. At this point, peel off the protective film from the double-sided tape that comes with the rain deflector, being careful not to let the adhesive surface collect dust. Align it with the edge of the window frame and press from the center outward to ensure the adhesive fully contacts the car body. Remember to press firmly on each spot for about 15 seconds. For rain deflectors with clips, gently insert the clips into the gap of the window rubber seal, then lightly tap them into place with a soft hammer. Try not to open the windows for two days after installation to allow the adhesive to fully bond. Choosing high-quality transparent acrylic material will make it more durable.
Once when helping a friend install rain guards, the key was patience and attention to detail. First, clean the window frame with a damp cloth and neutral detergent, paying special attention to accumulated grease. After disinfecting with alcohol, wait until the surface is completely dry, otherwise the adhesive won't hold well. When peeling off the backing tape, don't remove it all at once—peel half first, align it with the window frame, and then peel and stick gradually. After installation, press the rain guard firmly with your palm to ensure it adheres tightly to the body. For clip-on designs, use a small pry tool to gently lift the window seal and insert the clip, being careful not to damage the seal. Avoid rain or direct sunlight immediately after installation, and wait 48 hours before using the window normally. It's recommended to use models with 3M adhesive tape, as they withstand bumpy road conditions well.
The most important aspects of installing rain guards are preparing the tools and following the correct sequence. Gather tools like non-woven cloth, alcohol, and a small pry bar. When cleaning the window, be thorough, especially using cotton swabs to remove dust from the rubber seal gaps. Before peeling off the adhesive backing, test-fit the position to ensure the rain guard matches the window contour. Apply even pressure during installation to avoid partial adhesion and subsequent detachment. For clip-on rain guards, align them with the rubber seal groove and insert until you hear a click. Avoid opening the window for a day after installation to ensure adhesive stability. Remind yourself to choose rain guards of the right size—I've seen cases where incorrect sizes were forced on, leading to cracks.
