In order for paint to bond to galvanized or zinc coatings (I think aluminum too) you have to "pickle" it .......ie vinnegar ect
just do a search on the net for the subject it will explain better
I used to have to inspect coatings on (galvanized) beams and decking under NACE II requirements we were alwayse required to "pickle" the coating before application of any epoxy or oil baised painting or fireproofing systems
