How to Fix Wavy Patterns Caused by Sun Exposure on Car Film?

[LeRhett]

For wrinkled car film, you can try using a hairdryer to heat the wrinkled area to speed up the smoothing process. If this doesn't work, the issue is likely due to improper installation or poor-quality film, in which case the film needs to be reapplied. To prevent this, it's advisable to choose high-quality film and have it installed at a professional maintenance shop. Here are some additional details: 1. Risks of Low-Quality Film: Poor-quality film has a shorter lifespan and can compromise driving safety. Under high temperatures, the adhesive in the film may melt, increasing safety hazards. Such films often contain harmful substances like formaldehyde and benzene, which can be released with prolonged sun exposure, posing health risks to occupants. 2. Water Ripples: If the film is applied in low temperatures, wrinkles or so-called water ripples may appear. This is usually normal and will disappear on its own—typically within a few days in summer, or one to two weeks in winter. High-quality heat-resistant films may take longer. If the wrinkles don't disappear, a heat gun can be used to speed up the process.
