OK, here's the deal.
I'm an architect. I'm working on a 1970 school building.
There's some "mansard roof" construction at an exterior overhang.
The sloped siding is "aluminum batten seam siding".
It's original 1970 vintage. At this point, it is somewhat oxidized and not looking great although it is mechanically sound. I don't want to pull it all off and recreate it.
From recent investigations into detailing, I am wondering if we might approach this with compound/polish and a DA? I'd have to guess at how aggressive a compound/polish and what color foam pad to use, but it seems like in general it might be approachable. One fear that I have is that treating the raised "batten" strips would tear the heck out of the pads in no time.
And then, once that's done, what sort of sealant woudl be most appropriate for raw aluminum.
We could clear coat it with an automotive catalyzed clear-coat, but then once that starts breaking down, it really is untreatable. I prefer a clear polymer sealant that can be stripped and refreshed as needed.
OK, send me your thoughts. Appreciate it.
