i like 3m products and pads for a compound and glaze with rotary...then finish with any wax you want carnuba based. for a compound to work you have got to have speed....finishes today, clear coats, are so much harder than the single stage paints of years ago...most people have heard horror stories of someone using a rotary buffer and cutting a corner of a fender right down to metal in about 2 seconds...now with foam pads and variable speed rotary buffers and many grits of compounds it is almost impossible to cut though clear to the base. use a wool and full speed and a harsh compound and you will...i have been detailing cars professionally for a couple of years now and all my daily riders are black. i use only rotarty on all my and customer vehicles. one draw back of the rotary is that it is messy...the stuff slings everywhere. if its not slinging there is not enough on the pad. da polishers tend not to do that...i joke with my friend about his porter cable da that he has a nice waxer....showed him yesterday on his jeep srt8 black. he had a couple of scratches that he claims will not come out...took them out in about 5 mins with a 3 stages compound and glaze and finished with 3m ultrafina....he is looking for a new rotaray buffer now....i have color-sanded upwards of 10 complete cars, use only rotary....a da is so safe because it does so little...get a rotarty borrow one and use it on the wifes car...you will not use a porter cable again. now i will get ready for every one that follows the heard and says zaino and porter cable da rocks the house.
