I've been chatting with the folks at "AlumiClear" over the past about doing my 1996 34' Front Kitchen. One of the key things to take into consideration is the polish that is used during the polishing process. Many of the polishes on the market have a certain amount of silicon in the mixture to help with the process of water repellant. The problem with this mixture (if you're planning to clear-coat after polishing), any auto-body shop runs in fear when they see silicon near their building.
AlumiClear has a polishing compound that "does not" have a silicon product as part of the formula allowing their clear coat to bond better, providing a longer lasting (less peeling) finish. In fact, they have a 3-5 warranty for trucks used in commercial trucking.

Looking to have this done over the winter, I have no problem being the test subject.
Time will tell.
