Product Reviews

1.Turtle Wax T-43 Headlight Cleaner and Sealant

Product Overview

Turtle Wax T-43 Headlight Cleaner and Sealant is a 2 in 1 sealant that is capable of not only restoring clarity to a headlight lens but also preventing the yellowing of the lens or the glass.

This sealant is one of the best headlight sealants available for your car. Its primary component is a highly protective OEM acrylic resin. This composite strengthens the sealant as well as prevents oxidation from happening over the headlight’s lens.

Oxidation can damage or corrode the lens, but this sealant prevents that from happening. Likewise, this sealant can prevent cloudiness from reoccurring as well. So your headlight glass or lens will always look clear.

One thing to note about this product is that you must use this sealant on the headlight lens regularly to maintain its clarity. Regardless of whether your car is new or old, regular use of this product is necessary to prevent the lens from becoming cloudy again.

What we like about this sealant is that it can be used not only on car headlights but also on plastic windows, plexiglass, and other translucent plastics as well. So, by picking this sealant, you can get other jobs done in addition to cleaning your headlight lens.

Don’t forget that you need to keep your taillights equally as clean as your headlights. But don’t worry about keeping your taillights clean as this sealant is capable of doing that as well. Using this sealant will help you to keep both your headlights and taillights crystal clear.

Finally, this sealant is compatible with other headlight lens restoration products as well. So, you can use along it with other cleaners or use it to clean your headlights if you want.


  • Quick sealing
  • Easy to use
  • Works as both cleaner and sealant
  • Effective on other translucent plastics
  • Can seal taillights as well
  • Prevents reoccurrence of cloudiness


  • Does not protect against ultraviolet rays
  • Must be used frequently to maintain lens clarity

2.Blue Magic 730-6 Headlight Lens Sealer

Product Overview

For keeping headlight lenses from fading following a restoration or filling in small cracks, Blue Magic 730-6 Headlight Lens Sealer is a reliable choice. Although some people mistake this for a restoration system, it is actually not.

It is a cleaner that you can use between restorations to clean your headlights. This means, you can simply use it with any restoration product, and you don’t have to worry about matching it with a particular restoration brand product.

This is without a doubt the best headlight sealer on the market as it can fill in even the smallest cracks that can occur on your headlight lenses. Not only does it fill in cracks, but it also helps in clarifying the headlight so that the light can shine clearly when you drive.

In order to obtain the best results from this sealer, you should use it when you are done polishing your headlights as a part of the restoration process. If you use it before polishing your headlights, you will not get as effective of a result.

You cannot use this sealer to polish your headlights. You have to use another product to polish the headlights first. But by using this sealer, you can make the polish last much longer than usual.

Do not spray the product directly on the headlight or taillight lens. If you do, the lens will become blurry. The best way to apply this sealer is with a cloth or microfiber rag.

Lastly, one bottle of sealer should last for more than a year without having to purchase a new one.


  • Clarifies faded headlights/taillights
  • Can fill in small cracks
  • Makes polish last longer
  • Works well when applied with a cloth
  • Lasts longer than other sealers


  • Will not work as a polish
  • Has to be applied between restorations
  • Cannot be sprayed on directly

3.Formula 1 615874 Headlight Restorer and Sealant

Product Overview

If you are having problems with cloudy, yellowed, and dull headlights, then don’t look any further. Formula 1 615874 Headlight Sealant will get rid of all of these for you. But getting rid of these factors isn’t the only thing this sealant will do.

You can use this product for protection against oxidation, weathering, UV light, oil, grime, and road dirt. So, you can prevent damage to your headlights and taillights by using this strong restorer and sealant.

This sealer will enhance your car’s visibility. Because it can deeply clean the headlight lens of your car, it will make your hazy and dimmed headlights a lot brighter. Driving at night and fog will be a lot safer after you use this sealant on your headlights.

The Formula 1 615874 Headlight Sealant is not only capable of cleaning the lens of your automobile’s headlight. It can also be used to polish hazard lights, brake lights, windscreens of motorcycles (if you have one), boat windows, and even the glass of a helmet.

You don’t need buffing wheels or sandpaper to apply this sealant to your headlights. It can be applied directly onto the headlights to polish away the cloudy, yellowed, and dull lens of the headlights.

Our final tip is to apply this sealant after thoroughly cleaning the headlights. Also, do not apply too much pressure while cleaning. Firmly rub the cloth in a circular motion to apply this sealant.


  • Works fast
  • Very easy to apply
  • Can protect against UV rays
  • Works with using only once a month
  • Doesn’t require much buffing or rubbing
  • No sandpaper needed to apply


  • Costs more than other sealants

4.TriNova Headlight Restoration Kit

Product Overview

The TriNova Headlight Restoration Kit is our final pick for the best headlight restoration sealant. With this sealant, you will get a sandpaper pad that you can use to apply this restorer to your headlights. If you don’t want to use the included sandpaper, then don’t worry as this restorer is compatible with other sandpapers as well. As the included sandpaper is not capable of doing heavy duty buffing, you can use external sandpapers for this job if you prefer.

UV rays can affect the lens of your car’s headlights if you don’t use a blocking ingredient with the cleaner. So, with any cleaner, your headlights will quickly become yellowed. To prevent this from happening, you should apply this restorer to your headlights.

This restorer not only helps to improve the conditions of your headlights but also helps to clarify the taillights of your car as well. So, you don’t have to get a secondary cleaner for your taillights when you choose this kit.

Most restorers have other unnecessary chemicals mixed with them that make them less effective when it comes to blocking out UV rays. But this product is a hundred percent pure OEM acrylic resin, which means it will always provide strong UV blocking.


  • Works with external sandpapers as well
  • Can remove yellowing, dull, and cloudiness from taillights also
  • Protects against UV rays
  • Works as a cleaner as well
  • No secondary chemicals mixed into the OEM acrylic resin


  • The applicator and sandpaper are flimsy

Best Headlight Sealant Buying Guide

Here is a quick guide to help you pick the best sealant for headlights easily from the products available on the market.

Protection Level

Before picking a car headlight sealant, check how much protection it can give. For your car, headlight UV protection is absolutely necessary to prevent yellowing, dulling, and cloudiness. So, be sure to pick a headlight sealant that will protect your headlights from UV rays.

Cost & Performance

If a sealant is costly, that doesn’t mean it will give you better results. Even a cheaper sealant can provide good protection. Ultimately, the quality and performance will depend on the brand and on the ingredients used in the sealant. For example, OEM acrylic resin is a highly effective ingredient for a sealant—products with 100% OEM acrylic resin are going to be more highly rated.


Just because it is a sealant, doesn’t mean it can’t be used as a cleaner or a protectant. Save some time and avoid buying unnecessary products by picking a product that can be used for multiple purposes.
