problem with chrome is it's to smooth for paint to stick really well.
you could rough it up with sand paper pre paint.
another option is acid. muriatic acid is the name its sold under, is actually the old name for hydrochloric acid as i recall loves eating non-ferrous metal... ie. the nickle in the plate. i can explain why, but it involves a chemistry lecture. the stuff is available at hardware stores. usually in 40% form. you can cut it with water to make it less reactive.
i've used it at shipyards to strip everything off navel brass fittings. does a great job.
oh yeah, watch out cause it'll eat through concrete.
it ate right into a jetty once after sitting for a few minutes. not pretty.
