Rather than have the rubber rot out and the bands slip, or have the bands
raised up from the tanks, I ignore it. Painting helps a little, but the
reason I do paint them white is really so that is so that my buddy can
easily see me in bad vis or in the dark. The oxidation tends to be
self-stopping. The patina of oxidation forms a barrier to further oxidation
or galvanic action. Besides, by the time you fubar a tank from that it will
be time to discard it anyway.
