Bob,
Ah, you must be talking about the home of Mt. Gay rum. Sadly, I have never  
had the opportunity to visit this meca, but should probably try to get there  
before I die.
The epoxy that I used to do the repairs to the slot was a two part marine  
grade epoxy in stick form that was purchased at a local hardware store. It  
worked well to fill the voids and was such that I could shape it nearly perfect  
to eliminate much sanding. Trying to do much sanding laying on your back in  
cramped quarters is not my idea of fun. It seems to have held so far without any 
 other reinforcing. I guess time will tell how it stands up to NORMAL use.
 
Rummy
