primer for brass/bronze

i stripped the 9 portholes on my 41c down to bare brass/bronze i am going to paint them with awlgrip.
looking for a recomendation on what to prime them with
thanks mark

mark, i would check with awlgrip, and see what the recommend

Mark,

I believe you need to use Zinc Chromate primer. Interlux makes a two part primer for etching. I mixed and applied 2 coats, then two coats of Awlgrip primer, before painting the top coat. On our 1969 model 53' MY has aluminum dodger boards running down the sides, zinc chromate was needed.

thanks so much for the response's,
here is what awlgrip says and i have heard this before
"sand all surfaces to bare metal, mix a pot of 545 anti-corrosive primer, brighten one port hole with 100 grit paper clean with denatured alchol and prime within 5 minutes of sanding"this is because the bronze emits a "grease" when sanded that inhibits any primer from sticking, 2nd coat of 545 within 5 days and proceed with topcoats
this is why i have problems getting paint to stick to props, rudders, and struts
thanks again i thought i would pass this on
