remove chrome from plastic?

[William Hook <wghook@earthlink.net>]

The winshield wiper switch gave out on my wifes '72 TR6.    The
replacement switch came yesterday but the bezel/flange (integral with
the switch) is chromed plastic.  All of the other switches are black
plastic.  Does anyone know of a way to get rid of the chrome finish?   I
thinking about masking off the switch button and using a fine sand paper
to get back to black plastic then buff it back to a polish.   Does this
work? Other suggestions?

Thanks in advance,
