If you can be certain the grease doesn't have graphite as part of the blend it will be ok, but a lot of greases at parts houses have graphite additive.

I went ahead and popped for Aeroshell 33ms to err on the side of caution.

Depends on how much you want to buy. Loads of people o. EBay and Amazon sell small cups of the stuff that are more than enough for a barrel job or 2. The cheapest place I found for a full tube was:

Which is now Aeroshell 64. If you want to look around, Google MIL-G-21164D
