What is the difference between a carnauba and a sealant?
Application wise there is very little difference. Sealants are liquids just like many waxes are. You can apply them by hand or with a polisher or buffer. You apply it and buff it off just like a wax. The difference is appearance and durability. You know how if you dip your finger in candle wax it will form a shell around your finger? That is what wax does to your car. It creates a shell where the molecules are linked to each other and not necessarily to the car. When your car heats up it will actually shrink a little. When it cools down it will expand again. This shrinking and expanding will cause the wax shell to loosen and eventually melt away. A sealant is more like if you dipped your finger in super glue. You know how superglue bonds to your skin and is a major biatch to remove? Sealants aren’t nearly as messy as super glue, but the concept is similar. It will bond to your car on the molecular level as well as bonding to itself. This creates a very durable layer of protection that
