Opti-Metal Coat

I had mentioned before that my parents have a raw copper kettle that was given to them over 30 years ago as a wedding gift and since it is raw metal, it is prone to oxidation. My mom was tired of polishing it all the time, even with Optimum Metal Polish, so I brought it home and after polishing it, coated it with Opti-Metal Coat. It's a lifetime metal coating for finished or raw metals that can withstand up to 1,000ยบ F. No more need for her to polish!
