Essence isn't really designed for correction but it has ability to remove some light swirl's and mask remaining light swirls. If the car needs polishing you'd be better with a different polish.
It's a gloss enhancing final polish; but not like most finishing polishes. It has a tiny amount of cut, semi permanent gloss enhancing resins and protection, in one....but more ideal to have CarPro's nanotechnology coating applied over it as it's the ideal prep for it.
CarPro's Reflect finishing polish will do more in the way of correction.
