are the oil seals on a big 16g just rubber?

i believe i have the big 16g on my car. i have sealed every leak on the entire engine but i just noticed the rear main leaks just a hair, its just damp around the area not even dripping or anything but i want 100% oil leak free car so this bothers me. i was tempted to use that 6oz bottle of bars leak one seal oil seal treatment to stop this from getting worse until i feel like pulling the trans again , but i need to know if the 16g uses only a rubber seal to keep the oil in place or is it a metal piston ring type seal. if its rubber im not gonna pour that stuff in because this turbo is mint and i dont want that o ring swelling up and getting ruined

Metal. A rubber seal would destroy itself the first time the turbo reaches full speed.

i figured that but for some reason rubber o rings kept popping up under 16g rebuild kit. so i guess i should be ok to give that bars leak a shot

There are two rubber o-rings, but they're nowhere near the shaft. One seals the outer circumference of the compressor seal plate, the other seals the compressor cover.
