Default Gasket Maker

Going to be changing the rear differential oil in a couple weeks on the Dodge 3500. Question is instead of buying a gasket I'd like to use the silicone gasket maker or should I anaerobic gasket maker?

That is one vote for silicone. I have used the anaerobic before and it is real easy to remove. Expect I will never remove this cover ever again though.

I've tried it both ways but I pretty much believe in the old school way, CAT Greenshit to glue the gasket to one side, CAT Redshit to seal the other side. .

I use silicone, no gasket, just like all the automakers. Never had a lick of trouble with it.

I have never had a problem with silicone. I think the anarobic stuff is for joining machined surfaces.
