How to Apply Film on the Rear Windshield?
3 Answers
The workspace for applying sun film must be kept clean. The window glass must be thoroughly cleaned and dust-free, requiring repeated washing. Place the sun film with its protective layer facing outward on the exterior of the curved glass. Sprinkle water between the sun film and the glass, then use a temperature-adjustable hair dryer to heat the sun film. First, spray clean water on the interior side of the cleaned glass. Then, remove the protective layer from the sun film and spray water on the adhesive surface before applying the film to the glass.
Last time I applied tint film to my car's rear windshield myself, I realized the key lies in the preparation. First, park the car in a shaded area, thoroughly scrub the glass with a glass cleaner, then use a squeegee to remove all water marks and dust. Next, spray lubricating mist, peel off the backing paper of the pre-cut film, align it properly, and apply it. During the process, use a squeegee to smooth it out from the center to the edges, being extra gentle around the heating wires. The glass will appear blurry right after application; it needs to sit in the sun for two or three days to let the moisture evaporate. Most importantly, avoid rolling the windows up or down too soon, or the edges of the film may lift. Now, during summer drives, I can clearly feel the car interior is much cooler.
As an enthusiast who frequently helps friends with tinting, I find rear windshield films the most test of patience. Essential tools include a spray bottle, squeegee, and utility knife. First, clean the glass inside and out until it's mirror-like. Wet application makes the film prone to shifting, so a two-person adjustment is ideal. When squeegeeing, use a long blade at a 45-degree angle with steady pressure. Don't panic over small bubbles - just prick them with a needle to release air. Crucial reminder: never open windows before the film fully cures. One owner accidentally triggered the switch on day three, causing the entire film to peel. I recommend metallic ceramic films for optimal heat rejection without signal interference.
