[Boatanchors] "Chromed" Caps: Refinish Them?

[David Stinson]

I'm refinishing the covers on some of my Drake 7-line
equipment.  The handles on the side of the TR-7 and
front of the PS-7 have chrome-plated caps over the 
handle mounting hardware.  You can see the two 
on the PS-7 handle in this photo:

Mine have gotten cruddy and a little rusty:

Does anyone know a good way to refinish these, 
if not in chrome, at least in a clean and even 
satin finish?   Thanks.
