i use this maguiars stuff on the quattro..you pay full belt for it (of course) but can't find it anywhere for less than that..

and good old tesco's bumper shine spray - i can't see it on their website but it's in a big can with a dark red top and only costs a couple of quid and lasts through loads of car washes...brilliant stuff for bringing all the black bits back to life again..
