The problem with using all of these aftermarket sealants, is that no one really knows if they stand the test of time, and if they produce a thin enough seal to seal the cases.

Don't forget that there is no gasket between the case halves, so the sealant must be extremely thin there, otherwise it will affect the tightening, twist, and bearings within the case!

It is for this reason that the application process of the Loctite 574 is completely different than that of the Dow Corning 730 stuff. The Loctite should be spread evenly using an acid brush over all contact surfaces. The Dow 730 sealant needs only a very small, thin bead that is then compressed by the case. Laying on the 730 thick will produce too much thickness.

The bottomline is that you can just arbitrarily choose a sealant and use it without knowing in detail it's intrinsic properties. It may spread to thick, it may not compress enough, it may break down when in contact with aluminum or magnesium, or even motor oil. The Dow Corning 730 and Loctite 574 materials have been proven to work over the years - I wouldn't want to experiment with the case halves on assembly.
