is that after a major refit in NZ we were beating our way back to the US when the gooseneck bolts started backing out. The were hex head and well torqued before the trip. I backed them out one at a time, cleaned out as much Tefgel as I could and replaced it with Duralac. have not had a problem since.

I would still use Tefgel in other places but for cyclic loads and high vibration I am wary of the stuff.
