I had my car professionally detailed once, it was the best £200 I’d spent on the car. It was a fair number of years ago but back then the detailer told me he’s just applying his everyday wax as a finishing product. He pulled out of his kit a tub of other wax and told me I use this wax on the premium level details, it cost nearly £600 per tub, about the size of a tub of grease.
Cant remember brand names I’m afraid.
To keep mine looking good I use Autoglym products and Turtle wax.
