Bit of a specific one but I'm hoping someone here has experience. My father in law has a Wraith and he's been taking it to the same generic wash spot for years. Last time I looked at the paint closely there were fine swirl marks all over which I'm pretty sure came from their brushes. I want to find somewhere that actually uses proper methods for cars like this. I came across Premium Rolls Royce wash in Dubai Investments Park (https://royalprinceautocare.com/service/rolls-royce-wash/) and it sounds like the right kind of place but I don't know anyone who's used it. Has anyone here taken a high end car there or somewhere similar? What should I even be asking them before handing over the keys? I want to steer him somewhere better without sounding like I'm telling him what to do with his own car.
