Is the keel sealed up???? Well that's the $10,000.00 question, and my chore 
to have handled before any lead goes in.

Just got back from good ol' West Marine with a gallon of blue bilge cleaner. 
I'm going to go pour it into the sump in the keel and see what happens. Best 
scenerio, I'll go out there tomorrow and it will all still be there and the 
sump will clean up spotless, OR if it leaks down through into the keel I'll 
know 
that I have an issue to deal with there. I'm expecting it to be OK but just 
want to be sure.

I suspect that the water got into the keel right at the union of the keel 
trunk wall and the bottom of the keel itself. There appears to to be a split 
there in the fiberglass that has expanded, probably from the steel ballast 
rusting 
out. Either way I am going to fill the split with high density filler and 
then glass it up. There were some drips coming from the front of the keel slot 
in 
that area after the boat was put on the stands and was sitting a little nose 
low.

The other possibilities,  although I think they are small, is that the water 
got in through one of the pins' holes. The pins that were in there were not 
glassed over. You could actually touch the end of the bronze pin flush with the 
outside of the keel. Not  sure if that's original. All the other Montys I've 
seen have always had the ends of the pins recessed a little and filled over 
with either glass or something like 5200. That's what I'll do with the new pins 
to alleviate that problem.  Of course that doesn't solve the problem if the pin 
in leaking on the inside where it leaves the keel cavity to cross the gap of 
the keel trunk. Not sure what I'll do there if that seems to be a problem.

Or, did the blistering let water all the way into the compartment. I don't 
think so. Even the biggest blisters did not go all the way through the 
laminate. 
They were pockets of water (acid) between two layers of the laminate that 
they had pushed apart, but still had solid laminate behind them.

As far as mixing the lead and resin first before installing it. Yes, I have 
considered that but I think that would make it much more difficult to get the 
ballast to flow in where I want it and also  I think that the ballast would not 
be packed nearly as tight becuase there'd be more resin in the mix. As long 
as enough resin penetrates to make the mass stable I'll be happy. If a few 
areas remain un-soaked but are locked between "soaked" areas I think it will be 
OK.  BUT .....it remains an option to try it that way and if the first way 
isn't 
going well, maybe we'll give that a try. It's hard to describe if your not 
looking at it, but getting the lead into all the areas I want it to go will be 
challenging.

Sounds like the thermal imaging thermometer would be a cool tool. I don't 
have one, but I think we'll be able to fudge along without it. We'll just make 
sure to go slow enough to let stuff kick before we move on. 

Thanks fo the input gang
