Odd marks on my mast

Thread starter #1
I am cleaning up my boat to get it ready to use again after many years in storage. In cleaning the mast i cannot remove a bunch of odd marks. They must be in the aluminum or anodizing. Is it something I should be worried about.

I have attached a picture.

Is it "pitted"? If so, it's corrosion from being up against a dissimilar metal in a salt water environment. Nothing you can do, but it should be fine.
