silicone grease on primary rubber seal

I just recently had the clutch apart to clean the plates and am going to use atf in the primary. The previous owner used some gasket sealer before putting in the rubber gasket and I had a bugger of a time cleaning it out of the inner case where the rubber seal lives. I am thinking to use a silicone grease then install the seal as the atf wont dissolve it. Just want to check and make sure I'm doing the right thing! Would it be wise to put a little on the outer surface also after the seal is installed?

Never used it on this application but have on plenty of others and can't see any issues with what you plan.

The silicone grease I have is a bit rubbish when warmed up. It basically turns to liquid and just drips off! Is there better silicone grease I should be trying ?

I just use yer normal regular grease on this seal personally, just a very thin smear.

Never gave heat a thought! Just did a quick search and found there is heat resistant grease. Will shop around and see what I can find. I would like to go that route if it avoids the grease getting soupy with heat

"Electrical utilities use silicone grease to lubricate separable elbows on lines that must endure high temperatures. Silicone greases generally have an operating temperature range of approximately −40 to 200 °C (−40 to 392 °F) with some high-temperature versions extending this range slightly"
