A lighter weight less messy method is to
impregnate BID with RTV. Buy it
in caulking tubes for less cost and easier handling.
Lay out the size and shape piece you need on Saran
Wrap. squeegee on
1/8" RTV and lay down the ply of BID. Add some
RTV on top and cover with
another piece of Saran. Get something round and
hard like a deep well
socket or rolling pin and work the RTV into the BID.
Peel off one side of the Saran and apply the
RTV/BID RTV sandwich to the
desired spot. It will cure in about 24 hours IF
you remove one side of
the Saran. It has to have air to cure.
Have fun. It is great material but doesn't hold
well under AV-Gas
soaking.!

Terry, what is the temperature range of the RTV as
compared to silicon material. The nose gear socket
goes through my firewall at a rather irregular
angle, and runs through a reinforcement bead. If
the RTV comes in some high temp mixes, I'm thinking
that this would make for a better firewall seal.
