I'm changing the rear bearings on my explorer today and will need to get some rtv for the rear diff cover. Anybody know if any rtv will do or is there a certain kind? I'd like to just use permatex black so I can use it for other stuff too. EDIT: Haha this is what I get for searching http://www.permatex.com/products/Automot...rtv_sealant.htm Anybody know if this stuff is available locally? If not, what else can I use? I don't want to use a gasket because I have to do a bunch in the future.
