/this is the first time I have had a car ceramic coated, I was really astonished at the finish it gives, its literally like having a layer of glass over your paintwork!
my detailing guy has advised so long as I don't take take to a car wash where they use truck was it will last around 2 years, without additional waxing, I asked about waxing and has you mentioned, most waxes contain solvents, so advised long lasting waxes that you can layer, this will build another sacrificial layer before the ceramic, I have always been a fan of the Bilt Hamber stuff so will be hitting it with some of that at the weekend
the paint on these cars is soooooo soft, it really needs a hard layer!!
