I guess amazon is going to be my best friend with regards to car cleaning products. Halfords is awful for detailing products. Just been to Tesco and they have a lot of Simoniz products at half price, I was particularly fond of this http://www.amazon.co.uk/Simoniz-SIM0010A-150g-Original-Carnauba-x/dp/B003SEXTYY at £3.00
