What is best to use to plug the several small holes in a skull so you can poura Bondo/fiberglass mix into the brain cavity? I have had some luck with latex sealing foam, but wonder what the pros use.

Hugh,
What is the purpose of filling the brain cavity? Sorry, but I just wondered. If you're using that to attach the skull to a plaque, it really isn't that secure of a solution. I've used a molybolt, like they use on gypsum walls, with better success and when I did use fiberglass or bondo, they were too thick to leak through any of the neve connections before they dried. I'm sorry for having a CRS attack, but I feel I'm missing something (besides my mind, LOL).
I'm with George on this one, Why are you filling the brain cavity?
The only thing that I can think of is to secure a mounting block into
the skull. If that's what you are doing, then the solution is to
lay off the resin. just use bondo and you won't have any more leakage
problems.(let it "set" for a couple hours before you put pressure on it)
Good Luck
Dave
Plug the holes with a little clay which you can remove when the Bondo sets up.
