i use autoglym bug&tar removal and glass cleaner,but i use maguires 3step protection on the car its self.i also use 2 microfibre cloths when polishing the car,(after applying wax/polish with a lint free cloth)i use the first to polish off the wax/polish,the second to buff to a high shine

ps; i tried both bug removers and found autoglym out preformed meguires,but meguires blows autoglym out of the water for polish/wax
