The traditional way is to polish it up then lacquer it.

Hi,

Is there any product that y'all know of that will prevent brass from
tarnishing/oxidizing? I am just about to inlay some 1/8" diameter brass
rods into a painted piece, and once inlaid, it will be difficult to
polish
the inlay should it need it. Thanks for any help.
