Should you buy car paint sealant? Paint sealant is a good idea, but you can easily apply it yourself and save the cost of a dealer or detailing specialist application.

Apply paint sealant yourself and save big bucks

Pour the sealant onto a foam application and spread it around. Wipe off the excess with a microfiber towel.

When buying a new car, you might wonder whether or not to have the dealer apply a sealant for $300-$400. Paint sealant really is a good product. But it’s nowhere near as perfect as the dealer would like you to believe. If you read the fine print on the “lifetime” guarantee, you’ll see that you have to bring the vehicle back for repeat applications on your dime. With routine reapplications, the paint sealant sounds more and more like, uh, car wax.

In fact, paint sealant is nothing more than a polymer-based car “wax” that seals better and lasts longer than traditional carnauba-based waxes. You can apply the same finish yourself for about $20 (Some of the best paint sealant products are: Meguiar’s NXT Generation Tech Wax 2.0, or Klasse High Gloss Sealant Glaze) are both available through our affiliation with Or, you can find an auto detailer shop that’ll apply it for about $90.
