I need to patch up a few spots that blistered on my keel. I have tried the zinc chromate alone plus bottom pain but it does not work. I know that I need to get to shiny iron to make the repair. What thickened epoxy have you use to make such repair?

After sanding the rudder I found that there are a few spots that are3 showing foam and the rudder is getting water logged. What epoxy or other methods have you used to make the rudder water proof?

Thanks,
