Do you use gasket sealer on an 8 3/4?

I usually just use the RTV of your color choice. I like the red. I rarely use the actual gasket.

I like the black or gray just for the appearances. make sure the thin bead is inside the bolt circle as well and.... if it's an on the car deal be sure and bail out some of the housing grease so it doesn't keep oiling the gasket surface. I just barely tighten a few nuts then torque them all down the next day.
