is that the stuff you can get in Halfords? It's actually a turtle wax product if it is.... Zymol Bathe is about £30 for 250ml. I prefer Zaino Z7 as a maintainence shampoo on cars that are properly looked after, but use either Meg's Hyperwash or Shampoo Plus for "normal" work. Chemical Guys Citrus Wash and Gloss is pretty good too.
