How to Choose Headlight Sealants For Car?

It feels great after we clean our headlights and regain that original color. But given how headlights stay close to the road, it is only a matter of time before they get dirty again. The best way to avoid that is by using a quality sealant.

But finding that can be a bit tricky as some products don’t provide the result you want. Some others won’t give enough protection and let the headlights yellow again.

But you can stay sure that you won’t face any of that with the ten best headlight sealants from our list. Most of them are two-in-one products that both clean and protect your headlights.

10. Formula 1 615874 Headlight Restorer and Sealant

It is still a recommendation to clean your headlights beforehand. You can easily apply it on a soft cloth and rub it on the surfaces in rotary motions.

Buying Guide

When making the list above, we have come across several sealants to check. Unfortunately, most of them didn’t hold the quality that we expected. So, we thought that you could also face that situation.

In the worst-case scenario, you may purchase a low-grade sealant for your headlight. It is true that most of the items on the market can more or less perform the sealing process. But to get the best one, consider following the guide below.

Always stay careful and read the entire product description before buying anything for your vehicle’s maintenance.

How Long Will the Sealant Be Effective?

The effect of the sealant won’t last forever. Most of the ones you find on the market have a longevity of 4 months to a year. Since sealers from different brands have dissimilar properties and elements, they have a vivid lifespan.

As a result, it is something to check. See how long the headlights will stay protected after each application. We should note that some sealants with short effective times often are easier to apply to balance it out.


Yes, not all sealants are compatible with all issues. Some work extra effectively against UV, while others ensure no oxidization builds up. On the other hand, you should also buy a suitable sealant for the materials of your lenses and covers.

Some protectants will be particularly for plastic, while others are for glass. Only when the sealant meets your requirements, then consider buying it.


This factor takes us back to the longevity of the sealant. You don’t need a large bottle if one has a long effective period. Only one application will be enough.

But if you need to apply it occasionally, you need at least 8 oz. You may also want to seal your taillights or brake lights. See if the sealant has enough amount for your need.

Simplicity of Usage

Not all sealants are as easy to apply as some. Our reviews above have some of them that come with sprayer bottles. So you can directly spray them on the headlights. Meanwhile, others may need you to rub the chemical on the surface using a soft cloth.

On the other hand, there are sealants that require a syringe or polishing machine to be applied. If you don’t have these tools, avoid those items.


It is the most important factor. It is an imperfect one if a sealant fails to keep the headlights clean for the promised time. You can read the customer reviews to ensure the effectiveness of the protectant.

Final Note

Headlight sealants don’t cost much. Most of them will be available for under $20. But replacing a headlight can cost up to $1,000. Keeping your headlights covered with a protective shield prolongs their lifespan.

So, you won’t need to change the housing unit that quickly. You have to make sure to clean your headlights in time if it gets messy.

Before you apply sealants, you should clean the headlights first. While most of the items on our list work as a restorer, we still recommend using a proper cleaning agent.

If the sealant doesn’t work well with the cleaner, you may keep a decent interval between the cleaning and the sealing processes.
