Frequently Asked Questions

What are the real benefits of automotive window tinting?

Automotive window tinting does far more than make your car look better. High-quality films like Union Window Films significantly reduce heat, block up to 99% of harmful UV rays, cut glare, increase privacy, protect your interior from fading, and improve overall driving comfort. Modern films also enhance safety by holding shattered glass together in case of impact. J9's Luxury Auto Detailing is an award-winning shop in the Colorado Springs area.

How long does automotive window tint last?

With premium products and proper installation, tint can last over a decade. Union’s carbon and carbon-ceramic films regularly exceed 10+ years without fading, bubbling, or discoloration. Lower-grade dyed films typically only last a few years before breaking down. Longevity depends heavily on film quality, installation technique, and sun exposure.

Should I install window tint myself or hire a professional?

DIY tint kits exist, but they rarely deliver clean results. Professional installers ensure the film cures correctly, fits the windows perfectly, and stays free of bubbles or contamination. Brands like Union Window Films also require professional installation to maintain warranty coverage—so hiring a certified installer is the safest, cleanest, and most cost-effective choice long-term.

How dark can I legally tint my car windows?

Window tint laws vary by state, and each window on the vehicle may have different legal VLT (Visible Light Transmission) requirements. Always check your state’s regulations or ask your installer to help you choose a shade that’s both stylish and legal. Professional shops stay updated on local tint laws and can guide you toward compliant options.

In Colorado the legal percentage is 27% on the front 2 windows.

Will window tint interfere with my car’s electronics or GPS?

Union’s films are non-metallic, meaning they do not interfere with GPS, radio, Bluetooth, or cellular signals. Some older metallic films from other brands may block or weaken signals, but carbon and ceramic films avoid this issue entirely. Always choose high-quality, signal-safe materials—especially for modern vehicles loaded with tech.

How do I clean and maintain tinted windows?

For the first few days after installation, avoid rolling down the windows or cleaning them so the adhesive can fully cure. After curing, clean tint with:

• a soft microfiber cloth

• a mild, ammonia-free cleaner

• gentle strokes to avoid scratching

Never use abrasive pads, harsh chemicals, or ammonia—these can damage the film. With proper care, Union films maintain clarity and performance for years.

Can window tint be removed if I change my mind?

Yes, tint can be safely removed—but it should be done professionally. DIY removal can lead to scratched glass, ripped defroster lines, and stubborn adhesive residue. A professional installer uses steam, controlled heat, and specialized tools to ensure clean removal without damaging the window.

How long does it take for tint to fully cure?

Most tint will look great within a few days, but full curing can take 1–4 weeks depending on climate and film type. Ceramic and carbon-ceramic films may take slightly longer due to their density. During this time, you may see small hazy patches or moisture pockets—this is normal and will disappear as the film dries.

Is ceramic tint really better than regular tint?

Yes—by a mile. Ceramic and carbon-ceramic films like those from Union Window Films reject significantly more infrared heat, offer better clarity, last longer, and don’t fade or discolor over time. Dyed or basic tints may look okay at first but degrade quickly and offer far less heat protection.

Does tint really keep my car cooler?

Absolutely. High-quality IR-rejecting tint can reduce interior temperatures by up to 20–25 degrees, depending on shade and film type. Union’s carbon-ceramic films are specifically engineered for maximum heat blocking, making them one of the most effective cooling upgrades for any vehicle.
