yes, most of that black primer will stay,I'd spray a few coats of high build primer for blocking,epoxy does not like beeing blocked
and you'll know it when you start sanding on it
spraying tintable sealer is also an option,
as for the color,I'd take a trip to your local paint store and check out their color chip books, IIRC,2000 Honda has a very nice candy-like deep gold,it was on their hybrid Insight
