I’ve been through all the shampoos worth talking about on only coated cars. Anti-Ageing shampoo is without doubt the best I’ve used on coated cars. Foams well, is slick on the surface and the cleaning power! Used on 8-month-old Gyeon Syncro coating and it left it looking like it was just applied. Revived dead spots around the lower parts of the car (beading again) and cleaned away all light contamination leaving the surface perfect to follow up with Overcoat or Cosmic Spritz etc. Truly amazing product. An absolute must if your serious about maintaining coatings.
