i give my self all day to do the engine,i give it a steam clean then i polish all the visible white paint eg top of arches around suspension turrets,battery tray etc etc,i then normally buff up my samcos(baby wipes ) to get the water marks off then i use autosol on all my crome&stainless . if you give it a good going over the 1st time then all youll have to do is keep on top of it once a week(espesially if your driving in this weather!)
