Installing Film Over existing Aftermarket Tint
Adding new window film over existing aftermarket tint may appear to be a quick way to make the glass darker, but it can create avoidable appearance, adhesion, and durability problems.
We recommend removing the existing aftermarket film, preparing the glass correctly, and installing one properly selected film.
Why we do not recommend layering tint
Uneven appearance
Existing film can affect the color, clarity, and finished appearance of the new layer.
Adhesion problems
New film depends on properly cleaned glass. An existing layer can prevent a reliable installation.
Unknown condition
Older tint may already be fading, bubbling, peeling, or separating from the glass.
Unpredictable performance
Stacking films makes the final darkness and optical quality harder to control.
The correct approach
For the cleanest and longest-lasting result, the existing aftermarket film should be removed and the glass should be thoroughly cleaned before new film is installed. This gives us a clean surface and allows the new product to perform as intended.
