I had my car detailed the day after I received it by a local place (Burlingame, CA) with a good reputation, Topline. The owner told me they used Klasse products and I'm glad to see from Artsci's thread, that Klasse is ranking highly. How should I take care of my finish between details? Should I add additional coats of Klasse sealant after washing? Or do I use Klasse all in one? What about detailing sprays such as Pinacle?
