I used the Fel-Pro OS 30777 gasket instead of using sealant when reinstalling. Much less mess, you don't have to worry about RTV floating around your engine, easy to remove in the future, and no leaks.

I used a razor blade to break up the old seal as much as possible and then gave it a few good whacks with a rubber hammer. Then you use a razor and acetone to clean up the mating surface. Just be careful not to nick the aluminum pan when rooting around with that razor. Oh yeah, and don't use your fingernails to remove the old gasket material, even with gloves on. The slivers will have no problem sliding under your fingernails and slicing you up.
