Painting wood or plastic to look like metal?

Does anyone here have experience painting wooden or plastic to look like real metal?

I'm painting a wooden sword and I'm looking for a metal chrome finish. I'd like it as close to a mirror finish as possible. I might make a plastic version at a later date.

I tried Krylon Silver spray paint and it looked like sparkly glitter crap (the cap on the can was deceiving). Then I tried Testors Chrome spray paint and that looks better but still not a mirror finish. I don't want to go and spend money on every brand of chrome spray paint is there any brand you'd recommended?

I've been told to spray many layers of chrome paint then wet sand it with fine grit sand paper, then it will look like a mirror finish is this true? I have no experience in any of this so any help would be appreciated.

Jam it back in, in the dark.

I grabbed a piece of foil just to see how it would look, but it gets various veins and crinkles. Bondo, sounds good to smooth the surface. I'll check if Kilz has a metallic line. I only knew them as a brand of primer. Thanks for your ideas.

There's nowhere I can't reach.
