I just had my black Cupra ST ceramic coated with CarPro CQuartz UK 3.0. It had a full decon, de-tar, clay bar and two stage polish pre application. I have CarPro Reload as a top up every month. I attached a Whites Detailing video the other day about a well known spray on wash off ceramic booster that left all marks on the black paint on an A35 Merc. Does anyone know which one it is?
