Although I use many, no favorites really, it seems like I use alot of "Black Magic" products(car wash soap, detailer, tire shine, wax). I have a stash (just like oil/filters) that I have purchaced on sale or closeout stores such as BigLots/Ollies. Mostly, wax while you dry and paint detail type products as this is about all I use after washing each time(my own vehicles). I do have some different waxes around and only use them once in a while and only on the top portions of the vehicles(hood, roof & trunk). With 4 cars in the family, I'm always cleaning one of them. And once in a while I'll take on a Detail Job. Have done detailing for over 35 years and I'm not doing much of it these days, just now & again. It's alot of work!
