hello guys,
I noticed these two oxidation points on the aluminum fuselage of my moses.
in October I had disassembled it as a mast because in winter I don't use it and it only had two very small white dots, which I cleaned.
how to intervene?

Looks like the fuselage has been scratched and now corrosion has started under the anodised surface.
Remove all corrosion products by mechanical means, eg sanding, file, grinding etc.
Apply a aluminium surface conditioner, it’s an acid that removes any remaining corrosion products, we use a product called WO1.
Apply a chemical conversion coating, another type of acid which provides a anodised finish, we use a product called Alodine 1200.
Prime the surface with a quality primer, we use a two part epoxy.
Top coat as required.
Now you probably won’t have access to the above chemicals as they are aviation specific, maybe a boat yard could help, but you might find alternates by googling. You could also sand blast the area prime and paint, not a permanent fix but will give you a couple of seasons then replace the fuselage.

I had some surface oxidation, then I just cleaned it well and applied turtle car wax. Never saw it again
