I used Zinc Chromate to prime the outdrive. What do you use to touchup/paint the (copper) heat exchanger?

thanks

On the can of my zinc chromate primer I have it says its for aluminum and galvanized metal. Im not sure it matters. Zinc chromate is used for adhesion to those metals. I would personally look for a heat resistant primer.
