Spray sealant products contain cleaners and micro-abrasives. This combination provides a product that tackles fine swirls and provides gloss. The sealant spray elements help to protect the shine for longer than a regular polish. This type of clear sealant spray will also provide some hydrophobic protection too.
You can use a spray on sealant on wet vehicles to boost existing ceramic coating performance. This will increase the hydrophobic function and help prevent water spotting.
