If the aluminum is pitting with corrosion, the corrosion isn't protecting the spar.

Paint will protect the spar from further damage. Properly prepping the spar with a good metal primer paint and then using either a two-part epoxy or polyureathane paint will last quite some time before requiring re-painting. It will last longer with a good paint job than it will without one at this point, based on the description.

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.
