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.
