<p>[QUOTE="Kevin Mader, post: 6572340, member: 106826"]There’s damage between 9 and 10 on the 85D related to split plating and the effects of hydrozyncite. Dipping in acid will remove the hydrozyncite and leave voids in areas were the substrate zinc is missing. This is related to sharp edges and thin plating stretching even thinner. It doesn’t take much to compromise a thin barrier like copper while in your pocket or circulation.[/QUOTE]</p><p><br /></p>
