Why are there many small dots on the newly installed front windshield film?
1 Answers
The main reason is that some dust fell during the film installation process, causing these dust particles to be trapped inside. Below is an introduction to the causes and solutions for small dots appearing on the film: 1. Difficulty in shrinking and fitting bubbles at the edges of the front and rear windshields: The film edges are cut by pressing against ceramic dots, which then creates bubbles inside. Solution: After pre-shaping, perform precise cutting along the smallest edge of the ceramic dots during fine trimming. This makes it easier to fit and remove bubbles inside, especially for dry adhesive films. Avoid pressing against ceramic dots during cutting, as this can make fitting even more difficult and may even render the entire film unusable. 2. Difficulty in fitting bubbles around the defogger lines on the rear windshield: The rear windshield has defogger lines connected to ceramic dots, making it hard to fit bubbles on both sides. Solution: After pre-shaping, cut along the smallest part of the ceramic dots during trimming, avoiding pressing against the dots. When installing the film inside, please note that bubbles may appear where the film presses against the defogger lines. These bubbles must be transferred to the blank areas between the two defogger lines. Use a heat gun to shrink the film again. For glass with more prominent defogger lines or metal lines, dry heat pre-shaping is recommended.
