I plan to use the Sherwin Williams Wash Primer (P60G2 & R7K44) for general priming of the aluminum parts. While I was picking some up, I asked the guy at the counter for some Zinc Chromate in a rattle-can for small areas and touching up power-coated steel after drilling. He gave me a product called "Zinc-Clad Cold Galvanizing Compound (143-0255)". I don't know much about primers - other than what I've read in Van's manual and through the forums here, so my question -
Is this Zinc-Clad the same stuff as Zinc Chromate (or similar enough to use)? The Zinc-Clad says it's 97% Pure Zinc Dust and used to prime structural steel, wrought iron, etc. in marine, automotive, farming, etc. applications.
It lists as ingredients: Zinc, Propane, Butane, Methyl Ethyl Ketone, V.M. & P. Naptha, and Toluene. No Chromate - but since I don't know what Chromate is - maybe it's the same stuff?
The guy at Sherwin Williams says it's ok for aluminum, and one of the tech guys at Van's says it's probably ok, but I thought I'd throw the question up here to see if anyone has used this stuff or knows more about it.
