Hi Jamie
I must admit I used to be a Autoglym enthusiast (used it on all my cars over the last 12 years) but have found Meguiars is the way to go with black, I use the three part system takes a while but wow what a difference! Using the detailer inbetween waxes is very impressive as well
Just trying rim wax on the wheels for the first time only a week so far but they look good so far and thats with the rubbish weather we are having and a couple of hundred miles.
