Hi guys, reading your posts with great interest. I dunno if you can get it where your located but, Turtlewax scratch and swirl remover is simply amazing on black cars. I used this on my wifes 2 year old mitsibushi lancer and the swirl and scratches came out with little effort, furthermore I never even used a electric polisher either, all by hand. Here is what I did.
First wash and dried the car, second used Turtle wax swirl and scratch remover panel by panel on the whole car as if I was polishing it. Thirdly, polished the whole car with Autoglym resin polish, fourthly, I waxed it with Swissvax polish. The car came up better than new and with a wet look, reflections were awesome.
I am currently testing all tyre shine products and have a garage full of this stuff as I am not completely satisfied with the results of the ones I have previously purchased.
Hope this helps. I am a car and detailing fanatic by the way I will buy anything regardless of cost to enable my FX to outshine others as well as for my own satisfaction. People here in Taiwan just see a car as to get from A to B, not very often do people take care of their cars or even give it a polish and wax, like perhaps westerners do, its shocking. I always feel that people who drive very dirty cars are also dirty people with a dirty house and have no sense of respect!!
Unfortunately I cannot post full size photos of my new infiniti FX35, I really want to show it off here and let you see the reflections I get, but there again the FX is only a few weeks old so one would expect that it shines well. I would say though that I have managed to get this SUV shining 100% better than when it was delivered to me and I am sure the sales staff and mechanics were surprised by it when I returned to infiniti for its first service......
