OK guys, so with all the talk about the best technique to clean one's cladding, I stumbled across...ahhh, researched the issue and came across this product called 303 Aerospace Protectant.
It is excellent !
No hassle, no sweat and it utterly renewed the appearance of my cladding.
I found it at,

Just a suggestion to try it. I also purchased a number of other car care products that I also had never heard of, or spotted in the auto stores. I think you guys may enjoy wandering through.
Take care.
Max.
