What’s the Proper Way to Insulate the Brass so that it Doesn’t Tarnish?

by Wayne Kiser. On several pieces I have created I’ve included brass rods, tubes, etc. What would be the proper way to insulate the brass so that it doesn’t tarnish? I have found that if I use lacquer, in time, the lacquer will stop adhearing to the brass. Thank you. Wonderful site! Best, Wayne
