FAQ

  • Does Window TInt block heat?

    Yes. High-quality ceramic window tint can block up to 97% of infrared heat, helping keep your vehicle cooler and reducing strain on your A/C. At TNTZ Auto Care, we focus on heat rejection—not just darkening the glass.

  • Will Tint Fade over time?

    Premium window films are designed not to fade, bubble, or turn purple. Lower-quality dyed films are more likely to fail over time, which is why we only install high-quality films backed by manufacturer warranties.

  • How long does it take for the tint to fully dry?

    Window tint typically cures in 3–5 days. In colder Missouri weather, curing can take up to 2 weeks. During this time, light haziness or small water bubbles are normal and will disappear as the film fully sets.

  • What's the Length of the Service?

    Most installations take 1–3 hours, depending on the vehicle, the number of windows and film type.

  • What’s the difference between shades (5%, 15%, 20%, etc.)?

    Tint percentages refer to Visible Light Transmission (VLT) — how much light passes through the glass.

    5% = Very dark (limo tint)

    20% = Medium-dark

    35% = Lighter and legal in many areas

    We help customers choose a shade that balances privacy, heat rejection, and Missouri tint laws.

  • What are the legal window tint limits in Missouri?

    Missouri law allows:

    | 35% VLT on front side windows

    | Any darkness on rear side and back windows

    | Windshield tint must be above the AS-1 line

  • How to clean Windows after tinting?

    Use ammonia-free glass cleaner and a soft microfiber cloth. Avoid harsh chemicals or abrasive tools to keep your window tint looking clear and lasting longer.
