Many vehicles are originally equipped with a differential cover that is sealed with RTV rather than a gasket. To learn why installing a Fel-Pro® differential cover gasket is a better way to seal this type of cover, check out this video featuring Technical Product Specialist Mike Hinderer and ASE Master Certified Technician John Gurnig of the Fel-Pro Field Test Garage.
Featuring proprietary application-specific technologies for a superior seal, Fel-Pro differential cover gaskets are designed specifically for the repair environment to help seal imperfect sealing surfaces. Mike and John review the advantages of installing a Fel-Pro differential cover gasket rather than using RTV. Experience the Fel-Pro Difference and see why we are The Gaskets Professionals Trust™.

Don’t waste your time with this flimsy crap…get a Lubelocker and you’ll thank me later. Sorry Felpro, but Lubelocker has got you beat big time.
Yeah, this is one application rtv wins out for sure, unless the lubelocker is in your budget of course.
For decades I followed old school advice, rtv on almost everything. Until, I decided to go by the book on the water pump gasket on one of my Jeep XJ’s and go paper gasket only. I could not get the tiniest leak to stop on my other XJ. It’s so tiny I haven’t even repaired it yet (3 years now). I’ve also used my right arm as my torque wrench forever on the non-super critical bolts (almost always successfully, +99% of the time). So, this time I also torqued to specs. The correct torque was probably the biggest reason it has never leaked though. As previous poster stated, cast vs. pliable (thinner) stamped seal are completely different animals.
