After I Buy 3M 39084 Headlight Restoration KitMy high school aged son has started a headlight restoration business using these products, because they really do work! It takes some time and is not always easy, but the results are fantastic. Make sure to follow the directions. If you plan on restoring multiple headlights, I recommend finding some 1500 grit sandpaper, which makes the job a little easier. It is a big jump going from 800 grit to 3000 grit.
As long as the headlights on not damaged on the inside of the lens, this process will sand off the oxidation and the scratches and produce lenses that look 90% new. However, the sanding process removes the UV protection. This means that the headlights will become foggy again much quicker without this protection. We have discovered a simple process that will extend the time before the headlights become foggy. Once you have finished sanding and cleaning the lenses and have them looking great, follow these steps.
Fold a Blue Shop Towel into a small square. Dip it in Mineral Spirits and squeeze out excess. Wipe a thin coat of Mineral Spirits on headlights with horizontal strokes.
Now dip another Blue Shop Towel in ½ Hellsman Indoor/Outdoor Clear Gloss Spar Urethane and ½ Mineral Spirits. Squeeze out excess. Using horizontal strokes, work overlapping coats of sealer onto lens. Don't drive for 30 minutes. This provides some great UV protection.
Here are all of the steps we have used with great success in restoring headlights:
