From what you have mate..

Wash
Polish
Wax

But i would sudgest getting a clay bar kit to remove all the bonded contaminants and get the paint feeling like glass.

With that it will go:

Wash
Clay
Polish
Wax

Nothing wrong with Autoglym mate, most people who dismiss it i believe are not using it correctly..Yes there are better products but for working by hand (rather than machine) i think you will be hard pressed to see a difference from one product to another

Hope this helps
