I'm building some modular cubicles for a small office and I want to use sheet metal for the wall surfaces. I need to use oil based paint for a certain effect (flicking the base layer of paint with mineral spirits to give a crater-like effect).

The metal is smooth and i'd like to maybe see the metal in the areas where the spirits wears away at the paint. So... is there a clear primer out there or can I just apply a layer of oil based paint directly to the metal? Does anyone have any pointers on prep and the best process for this?

It is not reccomended to apply oil based paint directly to galvanized metal as you can get what is call saponification which is were the paint reacts with the metal and peels off. I am not sure if there is a clear acrylic primer made for galvanized metal or not. If you can't find one you could wipe the metal down with lacquer thinner to remove the mill oil (this should be done anyway) and take you chance with the oil based paint directly on the metal.

I will let you know if I can find a clear acrylic primer for galvanized metal.
