Feedback I got from Privateer Press' staff painters is for best effect, you want to shade and highlight your metals exactly like any other surface. Dullcote and then highlight only the brightest points with a bright silver (radiant platinum, VGA Aluminum, mithril silver - or whatever the hell
GW calls their brightest silver now-a-days).
Paint should go overtop of dullcote with no issue.
An alternative is a light brushing of gloss only on the highest surface.
The trick is that too much gloss makes them look wet, but if you get most of the gloss off your brush (similar to drybrushing, but not nearly as much needs to be removed) then it will just knock the dullness off without looking wet. If you can keep the gloss out of the crevices it'll add a bit of contrast between shiny surfaces and dull crevices.
I think it depends how you want the models to look though, you mention that was feedback you got from Privateer's painters, I'd argue while Privateer's painters do an awesome job their metals are a bit on the dull side for my likings.
As for painting over dullcote, just remember dullcote is a lacquer, you can paint over it but leave some time before spraying it and coating over it so that the lacquer can outgas for a while before painting an acrylic over the top of it.
