Window tint improves privacy, comfort and looks. Here's how to choose a film and a shade, and how to stay legal.
Film types
| Film | Heat rejection | Fade resistance | Relative cost |
|---|---|---|---|
| Dyed | Lowest | Can fade/purple over time | Lowest |
| Metallized | Good | Good; can affect signals | Medium |
| Carbon | Good | Very good; matte look | Medium |
| Ceramic | Best | Excellent; no signal issues | Highest |
Ceramic is the popular premium choice because it rejects more heat without having to be very dark.
VLT: how dark is dark?
VLT (visible light transmission) is the percentage of light that passes through. 70% is very light, 35% is a popular all-rounder, 20% is dark, and 5% is "limo". See window tint visualizer for how each looks.
Laws
Tint laws vary a lot:
- Windshields are usually restricted to a top strip.
- Front side windows usually have the strictest limit.
- Rear windows are often more relaxed.
- Some places allow medical exemptions.
Check your local rules before buying; fines and inspection failures are common. More in are car mods legal?
Choosing a look
- Light cars (white, silver) get strong contrast from dark tint.
- Black cars look sleek and uniform with dark tint.
- Matching front and rear shades looks cleanest, if legal.
Installation tips
- Choose a shop that computer-cuts patterns and offers a warranty.
- Expect some haziness for a few days while film cures; don't roll windows down until told.
- Avoid ammonia-based cleaners on tinted glass.
