Here is a complete breakdown of the most common tint technologies:
1
Purple Tint (Fading)
Tint turns purple because the cheap dyes break down under UV exposure.
UV light destroys the blue dye first, leaving only the red layer — resulting in a purple appearance.
This problem does not happen with:
Ceramic
Nano-ceramic
Carbon
2
Bubbling Tint
Tint bubbles when the adhesive layer fails. Causes include:
- Cheap adhesive
- Contaminants during installation
- Excess moisture trapped
- Cutting corners during prep
- Low-cost film with unstable glue
Once a tint bubbles, it cannot be repaired — it must be replaced.
3
Peeling Edges
Occurs when:
- Film was cut too short
- Edges weren’t heat sealed
- Poor squeegee technique
- The shop rushed the job
- Low-quality adhesive
Properly installed tint should have clean, tight edges with no lifting.
4
Hazy or Blurry Glass
This is called optical distortion and comes from:
- Cheap film
- Uneven film layers
- Defects in manufacturing
- Incorrect shrinking technique
- Overheating the film during installation
Premium films avoid this issue entirely.
5
When Tint Gets Scratched Inside
Usually caused by:
- Dirty or worn window seals
- Pets
- Jewelry
- Poor cleaning habits
- Cheap tint with weak scratch-resistant coating
High-end films include hard coats designed to resist everyday wear.
