Rear Main Seal leak - quick fixes

Rear Main Seal leak - quick fixes
Guys,
My 97'Maxima has rear main seal leak for like more than 6 years. Never seen a drop on floor though. Recently I have been seeing a drop-or two once in a while. Again it's not a drip-drip but very small.
Couple mechanics I took to gave all vauge and different reasons. The last one I showed to said there is leak from rear main seal...plus something oil-filter housing/motor not sure exactly what he said. It is engine oil for sure and not other fluids.
After looking online I found I can try Valvoline MaxLife or ATP AT‑205 Leak Re‑Sealer.
If at all I should try any of the above...which one to try first?
Thanks,
Om

I've had the same leak for a while now with no plans on fixing it unless i see a significant drop in oil between changes.

Just recently had my tranny rebuilt in my Max. It has 180k and I doubt any of the seals have been changed. The rear main had no visible leakage whatsoever and the half moon had a very slight weep, not enough to even drip oil on the ground when driven daily. So based on that, I would listen to everyone else and plan on that your half moon seal is leaking.

Thank you guys for the inputs.
And how much does that half moon replacing costs?
I am not yet sure if I should spend few hundred dollars unless 1) I know what part is exactly leaking and 2) It needs to be fixed sooner or later.

Its gonna be more than a few hundred dollars to replace that seal. Shops will rape you on labor to replace that seal. There are a ton of components that have to be removed to properly repair it.
Oh and btw, there are no quick fixes for this sort of thing. Try them and you will ruin your engine. Stop leaks always do more harm than good.

You guys were right on spot.
Finally a mechanic has confirmed it's Oil Pan Gasket (Front and Rear Seal) Part 11211-31U00/10.
Now I understand the "half moon seal" what you guys were referring to.
But in addition to that he said there's also slight leak at the center and it is from:
Crankshaft Seal - Rear Part# 12296-31U20
It isn't dripping a lot may be a drop a day but slowly there is a big spot at my parking place.

you guys keep forgetting that our cars are close to 2 decades old. what a reliable and awesome car my max is!!! yes, feels like a money pit sometimes, but it's all worth it when you look at the odo and realize she's still keeping up with all the other cars on the road and still turning heads.
