I'm using red RTV. At the first sign or smell of smoke I'm heading for the
ground big-time. I think I need like 10 minutes max of protection in a
totally worst case. After 10 min, if it's still burning and I'm not on the
ground, well...

Lots of guys use it but if you really have a fire red RTV didn't last
one minute when I tested it.

It comes down to odds and your assessment/acceptance of risk. What are the
odds that you will have an engine fire in flight? If you have a fire in the
engine compartment what are the odds that your firewall penetrations will be
continuously exposed to direct flame? What are the odds that you will
detect an engine fire and get the plane on the ground before things get
really bad? Seems like the most common problem with engine fire stories
that I can remember is smoke in the cabin. If all you need to do is
withstand engine compartment heat without direct flame on the penetrations
and keep smoke out of the cockpit then high temp RTV outta do the trick. I
calculated the odds (totally went with my gut feeling) and determined that
the odds are very low that my well maintained and frequently inspected
engine will catch fire in the first place, and I further calculated that the
odds of an engine fire creating a continuous flame on a firewall penetration
are even lower and went with RTV. It's a risk, but not much of one by my
calculations. :-)
