#221 had Thiokol for the "mountain" of caulk surrounding the shaft  
log.  I'm pretty certain it was original.  My log was in good shape,  
but I removed the caulk just to satisfy myself about why it was there  
and what it was doing.  I went back in with polysulfide, which is what  
I understand Thiokol to be.  It seemed exactly the same (and more  
rubbery/resilient than Dolfiniite).

I think if I were ever to remove the shaft log that I would go back in  
with a fiberglass tube; however, since mine was in good shape and I  
did not remove it, that is only theoretical.
