On a repaint, which is not baked from the factory, you will have to wait for the paint to harden an cure for 30 to 90 days, according to the instructions of the painter. On a factory car, it's baked, and probably has been sitting around in shipping, etc. for a while, so detail away.
As for the buffer, you should really go and get the PC7424 or the 7336 kit (search for 4DSC's definitive thread on the PC. With a black car, you WILL eventually get swirls, there is no way around it. As a matter of fact, that will happen with any car, but it's just more visible on a black car.
