POLISHED COPPER COATING
WOULD YOU PLEASE TELL ME WHAT I CAN COAT COPPER AFTER I POLISH IT SO THAT IT WON'T TARNISH AGAIN. WHAT I AM POLISHING IS 1/2 INCH COPPER WATER PIPE. I AM USING THE PIPE FOR A WINE RACK.
THANKS,

Well, you can coat it with gold :-) All metals except precious metals tarnish. But benzotriazole ⇦ this on eBay or Amazon [affil links] and a number of proprietary agents will retard tarnishing for a while, and brass lacquer may be what you are looking for.

You can use Incralac ⇦ this on eBay or Amazon [affil links] - special lacquer for copper and its alloys (it contains benzotriazole)!
