I also use Maguires 105 and 205. I first apply 105 with the rotary pad then buff off by hand. Then apply 205 finishing polish and again buff off by hand. Make sure that the pads are damp each time to avoid any possible burning and to ensure a smooth action on the DA. I do this with a mist spray applied directly to the pad. I then apply a coat of hard wax to keep the shine in. All this of course after washing, claying and washing again. Don't do to large an area at one time, I usually split the bonnet, boot and roof into two parts. Make sure you mask all the chrome trim and rubbers first. Hope I am not preaching to the converted.
