I use the detailer on a ceramic coated car after a wash, as a topper, or to clean off light dust and rain spots. The product is high quality and easy to use as it does not smear and wipes off easily, leaving a glossy, slick surface.
Although it may not have the most gloss, slickness, or longevity as other detailers/sealants with ceramic, being carnauba based, it provides a deeper gloss, providing more depth to your paint.
Also ensures the longevity of your microfiber towels as there is no ceramic to harden on them.
