Essence sits between polish and protection: one step that adds gloss, fills light defects with a semi-permanent filler and leaves SiO2 protection behind. It suits a car that needs to look its best without a full multi-step correction.
On its own CarPro US expects around a year, but it recommends Reload or CQUARTZ on top: the water contact angle rises from about 90 degrees with Essence alone to 115 degrees or more.
CarPro US says that in less time than a conventional polish it can remove swirls, raise the gloss and lay down semi-permanent protection, and that its primer quality makes CQUARTZ easier to apply.
