1. Tape Your Headlights off with Painter's Tape
Before you get started with your at-home headlight restoration, tape your headlights off with painter's tape so that no sandpaper scratches your vehicle.
2. Apply Water and Sandpaper
Use a spray bottle to spray water directly onto the headlight as well as the sandpaper. Start with 400-grit sandpaper going in circular motions and then in horizontal lines. The water will help prevent the scratches from going too deep, and the horizontal lines will help keep the clear coat in place at the end. Repeat with 600- and 2000-grit sandpaper as well.
3. Wipe It Down with Rubbing Alcohol
Make sure to use a lint-free paper towel when applying the rubbing alcohol. This will help keep any residue off of the headlight.
4. Cover It with a Trash Bag for Protection
Cover the surrounding area of your vehicle – or the entire things – with trash bags. Cut out wholes for the lights and reapply painter's tape to keep the bags in place. Give the headlight one last wipe with rubbing alcohol and leave it for about 5 minutes to dry afterward.
5. Apply the Clear Coat
Read the instructions on the clear coat before you start. To keep it from dripping, apply the coat in thin, even sprays. You'll want to apply 3 coats total, and leave about 5 minutes in between each coat so they can fully dry.
6. Wax It
Wait a day or so for the headlight to fully dry, and then you can finish off the restoration by applying a coat of car wax for some extra shine and clarity.
A Note on Safety
According to car accident lawyers at Millar and Mixon, chain reaction auto accidents can often occur in fog, rain or snow. Make sure you have full visibility when driving in bad weather, especially at night, to help avoid an accident.
