How to Apply Headlight Tint in 5 Simple Steps
Step 1 – Prepare the Surface
- Clean with IPA or Rapid Prep
- Clay bar the headlight for decontamination
- Use masking tape around the light edges
Step 2 – Cut and Measure the Film

- Ideal for indoor work or calm weather (less dust)
Step 3 – Choose Application Method
🔹 Wet Application:

🔹 Dry Application:
