DA 7700 BB question...

[tbushnel]

I just picked up a NOS DA 7700 BB (thanks 11.4) and I will be installing probably next weekend. It will likely see some wet weather use, so I wanted it "overflowing" with grease (ok, maybe overstating a bit). Anyway, the factory grease is fine (nos) but I feel like I want to add just a bit so when I install the seals there is some overflow. I don't think there is enough grease present for that and I dont have anything other than Phil Wood grease to add.

I assume it is not a good idea to mix grease types, but if I could get confirmation on that that would be great.

Also, whats the easiest solvent to use if I were to start over and grease with PW. I have mineral spirits, acetone, the green stuff...
Any thoughts?
thanks,
ted.
