I too am normally an Autoglym devotee and i still swear by their super resin polish,extra gloss protection,glass polish and fabric shampoo to name a few,but i never rated their bodywork shampoo.It never really cleaned or protected as well as it likes to think it does.Tyre dressing wise-you still cannot beat 'Armour all tyre foam'.I used to work in a motorfactor then became manager of a car parts/accessory shop so had all these things at my disposal!

Definetly give the Turtlewax Nano-tech shampoo a go though-it impressed me!
