Dennis,
I have a crank up about the same age. I don't live near the coast so that is
different. I have used the LPS cold galvanize spray with great results. I
just sand it lightly, wash off with a little water, let it dry and spray a
couple of light coats. It looks new although a slightly different shade of
gray! Looks like good stuff...
A little rust in California isn't a real worry unless you are on the coast
and probably not even then on a fairly HD tower.
Regards,

I acquired an older ( 25 to 30 years old ) crank up and bottom section and
some areas of
other sections have a very slight patina of rust starting...The other
section's galvanize help up fine,,
so I guess the bottom section must have been hot dipped galvanize on a
Monday or Friday - Ha !
My research with friend who knows chemical processes have come up with LPS
Brand Cold Galvanize
in a spray can ( P/N 00516 ) and Liquid ( 00518 ) and all the specs seem
good.
So I don't re-invent the wheel in refurbishing the tower before erecting,
has anyone been down this road before
and tell me if the LPS brand is best - and what is best method of prepping
surface before applying.
I have been told to lightly sand with scotch brite but one person says then
to wipe down surface with a solvent
( what is best ) and other says no solvent needed after lightly sanding
surfaces with Scotch Brite )
OK you Ol tower sages...Pipe up amd let me know best method !

Tower will not see much rain out here in So Cal area but I am sure some
morning dew collects on surfaces
( Things don't rust very fast out here unless one is within 1 mile of the
ocean ! )
