Paint sealants are very similar to car waxes, but they use synthetic, man-made ingredients that are more durable than natural carnauba. They provide a very comparable look to traditional carnauba waxes, but they usually come in the form of a liquid gel rather than a paste. You will get slightly more protection from a paint sealant and a longer product lifetime. While the application of paint sealants is very similar to paste waxes, they can be a bit more finicky to apply evenly.
