Your Product is great! I recently finished some copper sculptures. (Norwegian Fjord horses) The biggest problem I have had in the past is the copper oxidizing within 48 hours.......making a dull unattractive orange color....especially where it was touched. Someone in the metal industry recommended I coat them with Sharkhide. I little skeptical, I used some on a test coupon of copper. It worked beautiful! They have not oxidized at all and that was 2 months ago. I have run the test piece though some heavy testing, from boiling water to corrosive agents and it really shines! Thank you so much for this product!
