USL window tint from the United States. Below is relevant information: 1. Precautions: Newly installed car window film hasn't fully adhered yet. Prolonged water immersion may reduce its viscosity, causing the film to peel off. Therefore, avoid water contact or rain for 3 days after installation. Wait 7 days before rolling down windows after tinting. The glass will be tight, and window operation might cause edge curling or lifting, potentially damaging the film. After installation, park in sunny areas to ensure moisture evaporation and better preserve the tinting effect. 2. Car film maintenance: Never use sharp objects to scrape stains on car film or harsh chemical solvents for cleaning. Gently wipe with soft materials like clean damp towels, sponges, or soft cloths.
