called into my local shell station today and was greeted by 3 pikeys holding aerosol wonder wax! 3.99 a can, offered me a free demo on my filthy dirty car, told them no thanks, so they then jumped at the next car. An 06 plate Audi A6 3.0 tdi avant in met/black which was also full of s**t and grit. they then sprayed what looked like pledge over the drivers door and proceeded to mix the grit with the wax on a bog standard mk1 yellow duster cloth. all i can say is OMFG you should have seen the door.looked like it was polished with sand paper. The poor bloke thought at first great deal this until he saw his door. PRICELESS
