I tried baby oil once, it made a right mess when the sun had melted it a little, then it rained - horrid grease slick all down your paintwork

I'v tried everything I can find, the worst is the Williams F1 super spandangle, and the best of a bad lot is the Auto glym fairy liquid gloop.
I decided at the weekend that any black plastic is either being replaced with fresh new items, or is getting colour coded. Cos I'm that fed up with plastic trim looking shabby.
Appologies for sounding really grumpy
