Hi Peter,
Your car looks stunning, are the wheels in shadow chrome because they look good. You certainly take care of it.
Good info on your sticky on claying never seen it done so hear are my concerns,
how does claying compare with other products such as Maguires paint cleaner for example, i would be worried that any grit picked up by the bar would and could scratch the surface several times, and surely it can't clean as well as a fine cutting paste /cleaner you indicate only light pressure is required which is diffrent to a paint cleaner even if the car is clean.
