I use Meguiars products and a buffer. I use the buffer to apply the wax and a rag to wipe it off. I just bought a new buffer with Velcro on the wheel. I also bought three different types of pads for it. I simonized the whole car with the pad that was made for that and then I waxed the car with the pad that was made for that. I still have deep scratches that were caused by the dealer wiping the car down
N while it sat on the lot but I don't have any swirls in the paint thanks to Meguiars and my buffer.
