[Public-List] Bulkheads

So what are people's favourite sealant? I've been using
BoatLife polysulfide sealant. Polyurethane  (3M5200 and Sikaflex)
is too permanent. Silicone is permanent enough and once you
use it, nothing will stick to where it has been.

I was reading a british sailing, which recommended a butyl sealant
which stayed sticky indefinitely, meaning that when the seal flexed
and split, it would just seal itself again.

Thoughts?
