How to Polish Off Mild UV Damage from Headlights
Posted: Tue Feb 09, 2016 4:43 am
In the recent months, my right headlight started to show some hazing from UV damage. Given that my car is parked outside and facing the south, the front of the car is often exposed to sunlight. Despite preventative measures, some mild UV damage started appearing on my headlight. Hence, I tried a technique to remove the haze using some Meguiar's products along with a foam disc attached to my cordless drill. The results were impressive so I thought to share the process in case others are starting to get this sort of UV damage on the headlights.
Materials I used:
- A cordless drill. Mine was a 18V cordless Makita drill with a 2 speed setting and variable torque control.
- A foam disc pad with a drill attachment. Mine was from a 3M headlight restoration kit.
- Meguiar's PlastX plastic polish.
- Meguiar's Headlight Protectant.
- A damp microfiber towel for cleaning.
- A dry microfiber towel for protectant application and buffing.
For starters, this is what the headlight looked like before the process. The haze at the top is the UV damage. UV rays from the sun eventually harm the plastic of the headlights and cause them to haze to an opaque yellow over time, significantly reducing light output. 1) The first process is to clean the headlight and then wipe dry. It's advisable to remove the headlight from the car, but it's not necessary. I did so because I was also replacing the bulbs, but it made the polishing easier. If you are going to polish the headlights with them on the car, it's a good idea to tape up the painted surface around the headlight with masking tape to prevent polish exposure and abrasives on the paint.
2) Set the drill to the low speed setting if applicable and select a medium torque setting. It's a good idea to start off slower. Apply a quarter-size amount of Meguiar's PlastX to the center of the foam pad that's attached to the drill. I obtained the foam pad in a 3M headlight polishing kit I've used before on a different car.
3) Contact the foam polisher to the headlight before powering the drill to reduce splatter. Then start the drill and move the drill slowly around the damaged area. Move the drill back and forth for a few minutes.
4) Wipe clean with a dry microfiber towel and check the haze. Reapply the PlastX to the foam applicator and repeat.
5) Once you see a reduction in the haze, set the drill to a higher speed (if applicable) and then set the torque setting higher, closer to the drilling torque. Reapply the PlastX and polish for a few minutes, moving the drill around slowly, overlapping the damage area.
6) Wipe after every few minutes to check the process. Once the haze is removed to your satisfaction, wipe the area with a clean microfiber cloth.
7) Apply Meguiar's Headlight Protectant to a clean microfiber towel and apply like wax by hand. Polish the headlight with the protectant and then wipe off clean. Follow by buffing the headlight with the microfiber towel. Repeat process until the headlight appears clean and clear.
Finished result:
