Paint Sealants combine the longevity of synthetic wax with the high gloss and depth of natural carnauba. Paint sealants typically will outlast a synthetic wax in terms of its duration. The sealant fills and hardens onto the paint providing an impenetrable barrier once applied, often lasting up to a year or more depending on conditions. Great for new cars wanting to stay new, or restored vehicles looking for added protection. Paint sealants seem to be gaining popularity as its benefits are more closely examined, including being budget friendly.
