It makes sense; the job of a primer is to adhere to difficult surfaces and to have a substrate for the paint to attach to. Zinc being more reactive than copper (biggest part of bronze & brass) and in an ionic form, there should be no (or not much) displacement. Ron Wild Cheri C&C 30 STL

Here's how: rough up the metal with some 80 grit sandpaper, then apply a couple of coats of zinc chromate primer. Then brush on your choice of bottom paint.
