Substitute for Zinc Primer



Hello to all on the list serve,

I am working with a metal fabricator who was designated Title V due to
his Vapor Degreaser.  Luckily, I have worked with him so that as of the
end of January 2004, he will no longer be using the degreaser.  

Part two of his regulatory issues is where I need your help.  He is
currently using a zinc primer with 6.4 lbs voc/gal. which puts him into
non-compliance with his permit.  His permit states that he must use
coatings with a 3.5 lbs. voc/gallon or less content.  He has said to me
that any time he tries an alternative primer, his product experiences
peeling or flaking of the paint coating.  

Does anyone know of any proven alternatives to using zinc primer for
steels and aluminum substrates.   I even pointed him in the direction of
the coating alternatives guide which he says did not help.  Thanks in
advance for your help.
