Keel covering peeling off

[karista]

Just had the boat hauled for a new bottom job, when the yard was pressure washing the bottom. big section of the covering on the keel wing tops came off right to its lead base material.
I have no idea what material Catalina uses to encapsulate the keel, but its razor thin in some section and certeinly is not adherring well to the lead material. I was thinking of just removing the rest of the covering and applying several coats of thickened Epoxy and then finish with the bottom paint! Any thoughts??

Before you put on epoxy you need to sand to bright metal (with suitable protection) and use an acid-etching primer.  I suggest contacting International Paint (now a part of Akzo Nobel),  They can tell you how to do it right so the coating doesn't  come off again.

Bernd : The material coming off is an epoxy filler over the lead.  Follow what Ted has suggested. 
From my readings I understand that you have to work quickly as lead oxidises fairly rapidly and the lead oxide is why the epoxy won't adhere.
