How to Install Rain Guards?
2 Answers
Use a clean cloth to thoroughly wipe the corresponding window area where the rain guard will be installed. Excessive dust and grit can significantly weaken the adhesive strength of the rain guard. After cleaning the installation area, peel off the first protective film, spray water on both the rain guard and the window, align it with the installation position, use a squeegee to remove excess water, then peel off the second protective film to complete the installation. Below are the drawbacks of installing rain guards: 1. Image distortion: Rain guards are films coated with a hydrophobic layer. When applied to rearview mirrors, they can cause some degree of image distortion, affecting the driver's judgment of the distance of vehicles behind and potentially creating safety hazards. 2. Residue: Low-quality rain guards may leave adhesive residue when removed, making them difficult to clean. 3. Glare: Depending on the materials used, some rain guards may reflect light under strong sunlight, impairing the driver's vision and posing safety risks.
I recently helped a friend apply rain guards to the car windows. The process is actually quite simple but requires patience. First, prepare the tools: rain guards, a spray bottle with soapy water, a squeegee, and a utility knife. Cleaning the windows thoroughly is crucial—both inside and outside must be wiped spotless and dust-free. When peeling off the film, spray water on the glass first to create a water film, which allows you to slide and adjust the position after application. Once aligned, slowly squeegee from the center outward to remove air bubbles and water droplets. Applying even pressure while squeegeeing is key—I found that going too fast can leave tiny bubbles. Leave about 2mm extra at the edges for better adhesion before trimming, as rushing with the knife can scratch the car paint. Overcast days are ideal for application, as sunny weather causes water to evaporate too quickly, leading to bubbles. The whole process takes about twenty minutes, and after cleaning up the details, avoid rolling down the windows for three days.
