OldGuyFlier-
Generally, unless the mast is stored indoors, leaving it on wooden blocks can be a really bad way to store it. Wood tends to trap moisture up against the mast and make a localized corrosion cell. Happens more to stainless than aluminum, but any place the two are mixed, you can have some serious problems.
It might be worth making a partial sleeve to go around the damaged area and then either screwing it or riveting it to the mast.
If you decide to use stainless steel fasteners, makes sure that they are coated with either TefGel, Lanocote or some other compound to help isolate the two metals.
Also, might be worth filling the slight space between the sleeve and mast with 3M 5200. This will add strength to the repair as well as seal out water.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I agree that the internal sleeve is preferred, and far less likely to chafe halyards and such...but it takes a good deal longer to properly fabricate and install one.
