[TheForge] Re: cold galvanizing

Most zinc rich primers are porous  and  need to be sealed to work in a 
harsh environment.  Acrylic paint also passes moisture mostly. The zinc 
must go down over a very clean surface without rust to work. It is not as 
good as hot dip by far. Alot of welded  galvy water  tanks are sold here on 
the coast and they use the cold galv paint on the beads and seams..which is 
where they rust out.
