Re: another how 2 clean 20 years of grime off mast?
aircraft and airstream aluminum is alclad and has a layer of pure aluminum clad to the surface and will prevent corrosion and polish to a shine. the untreated aluminum mast will not polish up like alclad and after many years of exposure is coated with a thick layer of aluminum oxide which prevents further corrosion. sanding it off is not a good choice unless you are going to paint. if you don't want to paint than wash it and keep it clean and go sailing
I thought Airstreams were clad in sheet stainless steel? The Airstream club used to have their annual meet in the town I grew up in and I never saw aluminium oxide on one.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
