Hi,
I'm looking for the type of prime coat and top coat for painting an above ground exterior black steel used for natural gas or propane. I have used alkyd anticorrosive metal primer and alkyd enamel before, but was told that I cannot use alkyd anymore because the product is not low VOC (Volatile Organic Compounds). Anyone know of a product that can be used here that is also low VOC?

Thanks.

Below 180F we use an epoxy primer and urethane top coat.
Up t 300F we use epoxy primer and epoxy top coat.

Generally we use Ameron or Carboline products.
 
Thanks DLiteE.

Anyone know if paints and coatings for outdoor use has any VOC level requirements? I have seen 250 g/L for interior ferrous metal substrates.
