[C320-list] Lead Fin Keel Coating Repair Advice - 2007 C320 MK 2

[Utility Email]

Fellow 320IA Members,

Looking for some advice here.  

I just hauled out our boat for a bottom paint and hull buff and wax and to replace my shaft log hose.  I am reapplying Petit Trinidad Hard Epoxy Bottom Paint.  

I found 7 dime-sized and 3 quarter-sized bare spots on the lead fin keel.  

Bright and shiny lead is showing through a few of them and a couple are showing dull pitted lead.  The depth of the exposed lead from the keel is just really the thickness of the bottom paint and, I am guessing, the original epoxy barrier coat over the lead keel.  How would you recommend re-coating these repair areas?  

1.  Apply a metal primer and then a tie-coat primer before applying the epoxy bottom paint?

2.  Apply a type of epoxy primer coat, then fairing compound, then tie-coat primer before applying the epoxy bottom paint?

Any advice would be really helpful.  

Thanks!

Dave
