Bumper chip

[Philip Warburton <cplimey@home.com>]

I need someone's expertise here.

The front bumper of my spit has a small patch of chrome that has been worn
away/chipped away whatever over the years.
It has a little rust on it (surface only and the area is about 1/2 inch wide
and 4" long - and it is not all rusty.
Short of re-chroming, what is the best method to cover it as inconspicuously
as possible?
Silver paint?
Some kind of magic "remedy" out there that someone has used?

TIA everyone
