How to Deal with Bubbles in Car Window Film?
2 Answers
Bubbles in car window film often need to be addressed. Here are the repair methods for bubbles in car window film: 1. If there are numerous large bubbles, it is usually difficult to smooth them out, and it is recommended to replace the film. In such cases, not replacing the film can affect the car's appearance and even driving safety, so special attention is required. 2. If there are not many bubbles but they are large, you can make a small cut and gradually smooth them out using a squeegee and a heat gun. 3. If there are few and small bubbles, you can puncture them with a needle and then flatten them.
I tried to fix the bubbles in my car window film myself, mainly by using a bank card to slowly push out the air. Bubbles are usually caused by dust during installation or improper application. If there are small bubbles within the first few days, find a cool time to gently scrape with a card, pushing the air from the center to the edges. Pressing a few times should mostly eliminate them. However, for large bubbles or if they've been there for a long time, it's better to remove and reapply the film to avoid obstructing vision and looking unsightly. My previous car had bubbles a week after application, and I spent half an hour fixing about 70% of them. Never use sharp objects to poke, as it can scratch the film or glass. Park in the shade when possible, as excessive heat can worsen the problem. In short, try DIY fixes first; if that doesn’t work, visit a professional shop for a new film. Before applying, make sure the glass is clean and dust-free.
