Video tutorial on how to refinished hazy/foggy plastic headlights by applying clear coat. This is intended to be a long term method compared to the other two methods which I have done in the past that was the wet sanding/polishing method and the method using strictly toothpaste. The headlights do not need to be removed from the vehicle or disassembled as I have shown the in the vehicle. Removing the headlights from the vehicle does help to eliminate the chance of any over spray from the clear coat or adhesion promoter landing on the paint which would need to be cleaned afterwards. This particular video was done on a 1997 BMW 540i E39 body style.
