[VAC] Aluminum Propane Tanks

["Gordon Glass" <gkglass@xxxxxxxxxxx>]

Hi all- new to this AS game with a 1953 [13 panel] 25' "Cruiser" but 
enjoying it greatly so far.

A couple of questions:

I saw something about aluminum propane tanks on the Airmark Airstream 
Polishing web site.  Does anyone have any experience with aluminum propane 
tanks? Good/bad indifferent?  If good, does anyone know a source for buying 
them?

On the subject of polishing an Airstream in general. Does continued 
polishing reduce or extend the life of the AS?  I read something somewhere 
about aluminum thickness in the 50's and how you could damage the thin skin 
by continued polishing. My partner, Debra, thinks we should polish......I'm 
fine with this but don't want to diminish this well preserved (and never 
polished) trailer.

Thanks much.
