Not if it's done properly.  The usual way to do this is vacuum
deposition of a thin layer of aluminium, followed up by a coat
of protective covering (such as a polyurethane varnish).

That's how most of the "chrome" switches, dial surrounds, etc.
on cars are done, as well as plastic parts for die-cast models.
It's a line-of-sight process, so it's relatively straightforward
to coat the outside of a lens cap without getting anything on
the inside (and, in any cast, you could stick it onto a piece
of sticky tape).

My father used to work for a company that provided paints and
varnishes to Ford, so they had a small vacuum deposition rig
in their lab.  I used to give him parts from my plastic kits
(bumpers, radiator grills, wing mirrors, etc.) to be treated.
