Is it necessary to apply film on the rear windshield?
2 Answers
Whether to apply film on the rear windshield of a car depends on individual circumstances. The following are the benefits of applying glass film and precautions after application: Benefits of applying glass film to cars: Applying film is to block sunlight, especially during midday when external glare significantly affects driving visibility. Film can effectively filter out such glare, and some films can also reduce direct UV radiation into the car. Additionally, film can prevent the shattering of window glass, which could cause cuts, by providing a protective layer that holds the glass together, preventing fragments from scattering even if the glass breaks. Precautions after applying film: Avoid opening windows arbitrarily because the heat-insulating film needs time to firmly adhere to the window. During this period, opening or closing the window may cause the edges of the newly applied film to lift or the film to shift if it hasn't fully bonded. If the window is accidentally opened without causing damage, it's best to simply avoid opening it unnecessarily. Also, do not direct the air conditioning straight at the front windshield. After applying film to the rear windshield, avoid using the rear defroster lines.
As an experienced driver who has owned several cars, I highly recommend considering rear windshield tinting. Without tint, direct summer sunlight makes your back sweat profusely, and the AC struggles to cool the cabin. After installation, the interior becomes noticeably cooler with excellent heat insulation that reflects substantial heat. Privacy protection is another advantage - outsiders can't easily see inside, improving anti-theft security. The UV protection feature is practical, safeguarding your skin from sunburn while preventing interior fading. However, avoid overly dark films as poor light transmission during nighttime reversing can compromise safety. Opt for certified products from professional shops - quality films last years without bubbling. Overall, this few-hundred-dollar investment significantly improves daily driving comfort, especially during hot weather or long trips, making it absolutely worthwhile.
