I would go with the treatment that VXorado suggested I just used it and it is better than the show room new for ease of application and lack of temperamental streaking. I have no streaking and the cladding looks fabulous. The worst part is taping off the areas you don't want to have sprayed. I was not able to locate the picture of the heat gun treated cladding I'm sure if I looked longer I would find it, but I really don't think that you would like it.
