[QUOTE="Shadowrider, post: 3141995, member: 3099"] Well now you know. Acid will in fact strip anodize but muriatic isn't the right one to use. We used a nitric bath. It needs to be strong enough to "hit" the anodize layer fast enough to not cause too much metal loss from the etching. I'd bet the anodize had been abraded out of those pin holes to an extent when you started and so you started etching base metal almost immediately. You check to see if the anodic coating is gone by checking for conductivity with a multi-meter. When it's conductive you are then etching the base metal away if you leave it in. [/QUOTE]
