Headlight UV sealant
 

I'm looking to seal my headlamps that were polished last year. They're starting to fog up already.

Amazon has some, but I was wondering if there was any that I could pick up locally?

Not quite the same thing as what you mentioned above, but if you've wet sanded and polished your headlights previously and looking to keep the headlights protected, maybe a clear coat with UV protectant like this might be a cheap and easy solution:

You might want to go with automotive grade 2k clearcoat instead. The coating is a lot harder and more durable than regular stuff. However, PLEASE use a respirator with a proper filter (P95?) and use in a well ventilated area because the spray is hazardous to your lungs.

You can find 2K clearcoat at Lordco. I tried using it to clearcoat my wing and honesty, it's real close to what you get from an average body shop given the proper preparation.

Spray Max 2k High Gloss Clearcoat aerosol

Ether a clear coat or a dedicated headlight coating like Opti-Lens by Optimum will do.
