One of the Dynon EGT probes on Cyl #1 on my O-360 was spitting some very small flecks of tar like substance out of the probe hole on the exhaust header. The probe had 1000 hours on it so I replaced with a new one, which is doing the same.
Dynon folks tell me that it eventually seals up. I am wondering if I should use a tiny amount of something like this or just let it seal up on its own?

The compound is approved for exhaust systems with a very high temperature range and high pressure.
Thank you in advance.
