Will Removing the Rear Window Film Damage the Heating Wires?
2 Answers
Generally, it will not damage the heating wires. Below is relevant information about automotive window films: 1. Definition: Automotive solar films, commonly known as explosion-proof films, refer to films adhered to the surface of car windows. In addition to providing heat and light insulation, they also offer explosion-proof functionality. High-quality explosion-proof films use a special polyester film as the base material, which itself has strong toughness and is combined with a special pressure-sensitive adhesive. In the event of an accident, the film holds the shattered glass in place, preventing it from scattering and causing injury. 2. Product Introduction: "Dyed films" are first-generation products, commonly known as tinted paper, characterized by strong light-blocking properties and easy installation. However, they do not provide heat insulation, are prone to fading, and may peel off. "Metal reflective films" are second-generation products that use new adhesives and thicker film layers to enhance explosion-proof effects. They offer certain heat and UV protection, with heat insulation rates ranging from 20% to 60% and UV protection around 80%.
I've seen many cases where car owners damaged their rear window defroster wires while trying to remove the tint film themselves. Actually, these heating wires are extremely thin, just like strands of hair. They're sandwiched between two layers of glass but located precisely on the surface where the tint film adheres. If you try to peel off the film directly with a blade or by pulling hard, you can easily scratch or break the heating wires. The correct method is to first soften the adhesive with solvent, then use a heat gun to gradually warm the edges before gently peeling off the film. If you accidentally break the heating wires, the defrosting function will be useless in winter, and replacing the entire rear window is quite expensive. So if you're not confident, it's best to have it handled by professional tint shops directly.
