Best Headlight Sealant

Buying a headlight sealant may pose some concerns. Chemicals are a factor that people may worry about, including how effective or too intensive the formula may be.

I have never used a sealant, nor cleaned my headlights – but I’ve noticed how the yellow tint makes them look old, and even worse, less visible at night. I’ve heard of the toothpaste method that apparently can clean your headlight lens.

While it seems like an interesting DIY, there is no scientific evidence to back it up. I’d much rather use a product created for sealing against moisture that can ease your mind more when needing durable protection.

Keep reading to learn the pros and cons of each sealant for your headlight lens.

Buying Guide: Things To Consider Before Buying Headlight Sealants


Ensure the headlight lenses are clean so they look brand new before applying the sealant or coating. A sealant protects against damage and at the same time seals out dirt from seeping in.

So, using a designated headlight cleaner first will help clean it fully, along with sanding.


This step is optional but is recommended before putting on any sealant on your headlight lens for transparency. Its purpose is to take off any yellowing by sanding the surface with wet grit sandpaper.

Then, follow up with a soft wet sandpaper or towel to smooth out any line residue made by the sandpaper for a smooth finish. After sanding you can apply the sealer or coating spray for optimal protection against damage.


Before applying the sealant, ensure that the headlight lens is cooled down. Ideally, the best results are to apply the sealant in the shade so no UV rays from the sun can seep in during the process.

Headlight Condition

It’s a good idea to examine the headlights to see if there are any cracks or broken areas before sealing. If they are cracked, you can temporarily extend the headlight life by using super glue with a sealant on top.

The sealant and glue will ensure no dirt or grime can get into the crack for however long the sealant intendeds to last.
