To help feed the boat kitty I import a very fine boat anchor from Tunisia. Arguably the best performing anchor made. They come in galvanized steel, stainless and aluminum. My problem is the aluminum models are painted rather than anodized. While I have not received any complaints the paint tends to wear off fairly rapidly. I am thinking about ordering them bare and having them hard anodized locally.
The real problem is that each anchor is individually balanced by pouring lead into an open pocket at the tip. Would the exposed lead cause problems in the anodizing bath?
