My Dad, W7PH, and OLD painter, taught me a painter's trick for painting on
new glavanizing to keep the paint from peeling.  Paint it first with
vinegar.  Apparently, the acetic acid in the vinegar reacts with the zinc in
some way that makes a surfce the paint will stick on much better.  We used
to do this all the time on new construction when we had to paint new
galvaized gutters.  The frustrating part of it is that you can't SEE that
you have done anything.  It's a lot of work and nothing looks any different
. . . The usual reward a painter gets is that he can see the fruits of his
labor . . .
