It has been extremely cold in the northeast this last week, so I have been working in the shop. Earlier in the year I had removed all the sea strainers, and brought them inside to restore. That seemed an ideal project for such a cold week.
There is one thing to remember, if you also decide to clearcoat any bronze or other metal components that come into contact with seawater. The strainers are a part of the bonding system, and while I am not going to enter into a discussion here concerning the merits of whether or not include sea strainers in the bonding system, if you do, that area must be cleaned of any clearcoat, such that a robust electrical connection is created between the casting and the bonding wire. A little corrosion guard can then be applied over the connection.
