[currrt]

I am using a multi-coat system from Interlux for my underwater bronze (propeller and strut). It is a pricey pain in the butt to do it, but it looks like it should work. Pettit has an "underwater metals kit" that is less expensive, but I do not know anything about it. Check this out: http://home.att.net/~curthauger/shaft_prop_strut.htm

Good luck.
