Protective coating for galvanized counters in a floral store [Alaska] 

+++

I am in process of remodeling our floral store and would like to use 20 guage galvanized steel for my design and sales counters. Lots of water, flower food, fertilizers, etc., will be in constant contact with the galvanized surface. Could you please tell me what I can treat the galvanized steel with that will prevent the white rust as well as other reactions from occuring? I would also appreciate your recommendations for ongoing maintenance. Thank you.

You must be highly enamored of the look of galvanized steel if you are eager to put up with the maintenance headache you already know that it implies. You will have to clearcoat this to prevent the white rust. You might see if you can buy the metal already clearcoated because getting paint/clearcoat to stick to galvanized steel is an issue. I think stainless steel would be a much better idea.
