What I'm trying to say is that if I/you were just about to line up on the grid OR it was "Happy Hour" at the Buffalo Bar THEN the absolute minimum of sealant on the mating faces is not gonna cause a problem.
Just don't expect it to fill any major gaps and stay there when the pressure is up, and do expect to fix the problem of why it needed sealant.
Also, some sealants are not coolant resistant. I believe nasty Threebond 1104 is. Well it must be as half the two strokes in Thailand have it dripping out of the engine.
