My understanding of Hylomar (from my RX-7 ownership days) was that is was developed specifically for use in o-ring sealing applications. Supposedly Mazda was having a heck of a time getting the large o-rings in-between rotor housing to seal and someone developed Hylomar for them and it worked like a charm.....but only in o-ring applications.

>The first thing that came to mind is the sealant I used for my old CB700SC engine, called Hondabond ... I see it mentioned on the Rennlist too. This is apparently like Permatex grey.  Then I remembered some stuff I used on the urq long ago called Hylomar.  This stuff is non hardening and is now supplied by Permatex too. Were I in your position, I'd go with the blue stuff.
