Apply a bead that is 1/4" to one surface and then mount the differential cover immediately. Finger tighten the bolts. Wait one hour for the gasket maker to set. Tighten to torque specifications (I think it's 30 ft lbs). Takes 24 hours to cure but you can put oil back in after torqued to spec.

A lot nicer than messing with rtv, and like suggested, it takes 24 hours before you're suppose to add fluid. I've always just put the rtv on and waiting about 30 minutes to tighten bolts, and then added fluid. I'd say 3/4 I didn't leak. Much nicer with the lube locker, especially if you're impatient like me.

Where does that requirement come from? No mention of it in the service manual. It says to apply the sealant, install and torque the cover, and add the fluid.
Same with the automatic transmission pan. No waiting.
It has always worked for me.

Apply sealant, put the diff cover on and finger tighten the bolts. Wait one hour. Then tighten bolts to torque specifications. Sealant will cure in 24 hours.
