A bump on the side of the keel was caused by water running down one of the 12 keel bolts. The water froze and pushed outwards. The bump is about 3"x4". I am told that we should just patch it when it warms up. How do we patch this? I was going to suggest the we just tap in the lead and file it smooth. In order to avoid this problem in the future we should pour antifreeze into the bildge area. Any suggestions.

Barrier Coat

Interlux...you can buy it at any marine supply store. Clean with solvent, sand, clean with solvent, apply barrier coat neatly, allow to cure fully, then sand it down and apply your AF paint.

sorry...not, barrier coat...

fairing compound is what I meant. You would then apply barrier coat over, and AF paint over that...sorry for the miscommunication.

This has some real

long term potential for problems. Yes, tap the lead back tight. The bulge is going to provide space for more water, more freezing, bigger lumps, room for more water...... Antifreeze will prevent the freezing of course. If you work carefully with your hammers you should be able to work the lead back to its proper shape with little or no trimming. When it starts to look pretty close, rub it lightly with a hard sanding block and tap the shiney spots down. The long term problem of which I spoke is the bulge caused by the freezing will cause the lead to let go of the bolts. So it is imperative that the lead be driven back tight against the bolt.
