As I have only asked for advice (and got it), today I thought I would put up a short note (probably what you already know!).
I finished the Autoglymn shampoo the other week and bought some Meguiars Gold class.
What a difference! Much richer suds and a softer feel to the water, and after a quick dry off with a micro fibre towel, the car looks though it's had a showroom wax!
Hats off to Meguiars - I am surprised how much better it is than Autoglymn.
Someone will now tell me there is something better than Gold class :-)
