Hello, next month I get now my first new car 😉 now the question arises how I should treat the paint best after the crossing 1; Meguiar’s ME G7164 Gold Class Car Wash Shampoo and Conditioner 2; Meguiar’s G18211EU Ultimate Paste Wax 3; Meguiar’s G7616EU Gold Class Premium Quik Detailer is this right to treat the new car like this? Thank you Martin
