I have a 6 inch single speed orbital polisher, its only a cheap chinese one of Ebay at £20 delivered bought a couple of years ago but still working well when it comes out twice a year, coupled with Meguiars Ultimate Polish it gives my black Panda great results & eliminates minor imperfections, the rest of the time it just gets Autoglym Radiant Wax Polish by hand which is a trade version of Super Resin Polish then a layer of Bilt Hamber Double Speed Wax on a regular basis which seems to work as the car still looks like new considering its not far off 4 years old
