Aluminion gearbox sealant.

[Scraperman]

I am in the process of putting new oil seals in an aluminium Superior gearbox off my Scag ride-on and wondered what would be the best sealant to use when re-assembling the two halves of the gearbox. The gearbox splits in half and I think I can see traces of the original sealant on parts of the mating surfaces. There was no gasket and so I presume that, because it is aluminium, that a sealant of some sort is used instead.
Thanks in advance for any help and/or advice.
