When tinting a vehicle, you don't always have to do the full vehicle. Many people opt for single-item applications to solve specific problems like glare, interior heat, or UV exposure through overhead glass.
Here is a summary of the most common "add-on" tinting options:
1. The Visor Strip (Eyebrow)
A visor strip is a band of tint applied to the top 4–6 inches of the front windshield.
The Purpose: It acts as "permanent sunglasses" for your car. It is specifically designed to block the blinding glare of the sun when it's low on the horizon (morning or evening).
Legality: Most states allow tint down to the AS-1 line (a small mark on the glass). Usually, a 5% (limo tint) shade is used here for maximum effectiveness.
Benefit: Reduces the need to constantly flip your physical sun visor down and up while driving.
2. Sunroofs & Moonroofs
While many factory sunroofs come with a slight "smoke" or privacy dye, they rarely offer significant heat protection.
The Purpose: To block overhead "greenhouse" heat. Since the sun beats down directly on the roof, this glass is often the biggest source of cabin heat.
The Recommendation: Ceramic film is highly recommended here. Because sunroof glass is horizontal, it absorbs more thermal energy; a high-quality ceramic film can block over 90% of infrared heat without making the glass too dark to see the stars at night.
The Myth: There is an old "pro-shop" legend that tinting a sunroof causes the glass to shatter. While thermal shock is a theoretical risk, modern high-quality films and professional installations make this extremely rare.

Key Differences: Sunroof vs. Moonroof
Sunroof: Traditionally refers to an opaque metal or glass panel that can be tilted or removed.
Moonroof: Technically a type of sunroof, but it is a fixed or sliding glass panel that stays in the car and usually comes with a fabric sliding shade.
Tinting Tip: If you have a panoramic moonroof (the kind that covers almost the entire roof), tinting it is one of the single most effective ways to lower your car's interior temperature.
