How to Install Car Sunshade and Heat Insulation Film?

First, thoroughly clean the car to remove dust, then park it in a clean, dust-free area in preparation for film installation. Measure the dimensions of all areas on the car where the heat insulation film needs to be applied. Cut the film according to the measured dimensions, ensuring it is not undersized. Peel off the film, evenly spray water on the adhesive side, attach the sprayed side to the car window, and use a soft squeegee to remove all water between the glass and the film.

When I applied sunshade heat insulation film to my car myself before, it was quite a hassle! First, I had to prepare the tools: a spray bottle filled with soapy water, a clean squeegee, and a utility knife. Before starting, the car windows must be thoroughly cleaned, leaving no dust or scratches from fingernails, otherwise bubbles will form under the film. Then, cut the film slightly larger than the glass, spray water while applying it, and gently squeegee from the center outward to remove water and bubbles. If any bubbles remain, carefully poke a tiny hole with a needle to squeeze them out. Remember to trim off the excess edges, or they might peel. My first attempt took two hours, and my hands were sore, but the car was noticeably cooler in summer. I recommend getting help or choosing a shady day to avoid film deformation from direct sunlight. After application, avoid washing the car for a few days to let the adhesive set properly.

I've tried applying heat insulation film several times and learned quite a few lessons. The key is thorough cleaning: first wash with glass cleaner, then wipe dry with a slightly damp cloth to ensure no grease or dust remains. Don't skimp on the soapy water spray - keep both the glass and film moist for easier positioning adjustment. After application, quickly smooth it out with a hard squeegee, using even pressure to avoid scratching the film. Be patient with bubbles - prick small ones with a needle to release air, while larger ones may require partial reapplication. Finally, check edge sealing to prevent moisture seepage. I've found rainy days better for humidity control, but DIY attempts had high failure rates. Eventually, I switched to professional shops - more cost-effective and quality guaranteed.

The basic steps for applying sunshade and heat insulation film are quite simple. First, clean the car window to ensure it's smooth and dust-free. Second, cut the film slightly larger than the glass size. Third, spray soapy water on both the window and the film. Fourth, align and apply the film, then use a squeegee to remove bubbles and air. Fifth, trim the edges and cut off any excess. It's best to wear gloves during the process and work in an indoor environment. After application, let the film dry for 24 hours without contact with water. When choosing heat insulation film, check the UV blocking rate; high light transmittance films are less likely to overheat in summer. Regular cleaning of the film surface can extend its lifespan and prevent scratches.

Applying a heat-insulating film really helps lower the temperature inside the car. Last summer, I replaced mine with a new one and noticed a significant difference. Before starting, gather the necessary tools: a spray bottle, squeegee, and film sheets. Cleaning is crucial—use a microfiber cloth to wipe the windows without leaving fibers. It's easier with two people working together—one sprays water while the other positions the film. After spraying, quickly apply the film to avoid bubbles caused by rapid water evaporation. If any bubbles remain after smoothing, let it sit for a while as the moisture evaporates and they'll disappear on their own. Avoid rolling down windows or washing the car for a few days after installation. A word of caution: low-quality films tend to degrade and discolor easily, so it's advisable to choose branded products or consult professionals for a more reliable installation.
