Frequently Asked Questions

What do you seal headlight lenses with?

Most headlight lenses are made of polycarbonate, which is a type of plastic. This material is very strong and shatter-resistant, but it can become dull and yellowed over time. You can seal headlight lenses with a clear polymer sealant to protect them from the elements and keep them looking new.

Clear polymer sealants form a protective barrier on the surface of the lens that repels water, dirt, and debris. This helps to prevent premature aging and fading of the lens. Sealants also make it easier to clean headlight lenses; simply wipe them down with a damp cloth when they get dirty.

There are many brands of clear polymer sealants on the market, so choose one that is compatible with polycarbonate surfaces. Follow the instructions on the product label for best results. In most cases, you will need to apply multiple coats of sealant for maximum protection.

How do you seal a headlight lens back?

If your headlight lens is yellowed, cracked, or otherwise damaged, you may be wondering how to seal a headlight lens back. The good news is that it's not as difficult as you might think. With the right supplies and a little bit of patience, you can have your headlight looking like new in no time.

Here's what you'll need: -A clean headlight lens (free of dirt, debris, and other contaminants) -Sandpaper (fine grit)

-Primer -Clear coat paint -Masking tape

Instructions: 1. Begin by cleaning your headlight lens with a mild soap and water solution. Be sure to remove all dirt, debris, and other contaminants before proceeding.

If your lens is particularly dirty, you may need to use a commercial cleaner designed specifically for automotive lenses. 2. Once the lens is clean, use sandpaper to lightly sand down any rough edges or areas where the clear coat has begun to peel away. This will help create a smooth surface for the new primer and paint to adhere to.

3. Next, apply primer to the entire surface of the headlight lens. Allow the primer to dry completely before moving on to step four.

What can I use to seal my headlights after polishing?

There are a few different ways that you can seal your headlights after polishing. One way is to use a clear coat sealant. This will help to protect the headlight from UV rays and keep it looking shiny and new.

Another option is to use a wax or sealant specifically designed for headlights. This will also help to keep the headlight looking its best and prevent fading or yellowing over time.

What can I put on my headlights to keep them from yellowing?

Your headlight's yellowing is most likely caused by a UV protective coating that has worn away. You can try to remove the yellowing with a headlight restoration kit, which you can find at most auto parts stores. The kit will usually include sandpaper and a polishing compound.
