This works
Wow!! I am shocked at how good this works. In addition to the fact that it works, it is Packaged with novice people in mind to get maximum results. This was worthy of before and after pictures; but, starting tge project, honestly didn't think it would result in the way it did.

Excellent results
I have an older truck with badly oxidized headlights. I saw this product advertised and decided to give it a try. It was amazing how easy it was to do. 3 step process and the most remarkable results! I had a question regarding the process, called the number on the QR code and spoke to a person! OhJoy!
More than helpful, put a whole new meaning to "service after the sale"I highly recommend this product and this company!

Not quite what I expected
Great price but the results, though they did improve the clarity, it was not the full results I HAD EXPECTED..
The foiled packages that had the oxidizer removal and ceramic clear coat were nearly dry when I opened them.
They should be made more wet when sealed and possibly better foil paqckaging.

Ruined my headlights! Big waste of money!
I decided to try this instead of soda bicarbonate and toothpaste to see if if would be oxidation cleared for longer. Big mistake, it made my headlights completely hazed making it even worst. Don’t waste your money on this or anything else. Soda bicarbonate and toothpaste is better and you can seal it with a lacquer or sealer. Big waste of money. Hopeflly I can fix them…😡
