I'm sure you have all been anxiously awaiting my report, so here it is.
I disassembled and cleaned my two loose sea valves with kerosene, dried them out and them reassembled them using the subject grease. It seems to be very tough stuff. In the first case, I hand tightened the flange nut and then held the handle while I tightned the lock nut with a 10 inch wrench. This sea valve operates very smootly and I can't imaging that it would leak. No amount of side pressure I could apply with my hand would cause it to lock up. In the second case, I did the same cleaning, greasing, and reassembly, but after checking that the hand tightened flange nut posed no problem to operation, I cranked down on the flange nut with the wrench and then added the lock nut. This sea valve operates as smoothly as the first. I don't think it is likely that one can squeeze Morey's Red #3209 off the barrel with even moderate pressure with a wrench. Side pressure has no affect on this unit either.
I am looking forward to getting Parfait out of the water and applying my new skills! If barnacles tend to grow in the open seacocks and freeze them up, do you suppose that stove polish would work there as well as it does on the prop? Maybe that is another experiment we can do.

Re: Bottom paint in the thru hulls.....
Ken,
I had asked the yard manager about critters growing just inside the thru hulls, and he said to use a 1/2" brush to reach up in there a little ways and paint them with bottom paint. Critters don't grow where there is no sunlight! So, you don't have to go up the tube very far. I don't think the stove polish would work, as you can't clean the surface before application.
When I disassembled the seacocks last Saturday, there were a few, very small, critters just at the outer surface of two of the 6 through hulls, they fell out with the application of a screwdriver!

Re: Critters.....
Another place to check for critters for those with the old fashioned engine intake strainer is inside the through-hull for the engine intake. I haul my boat every year so in my case they do not have a chance to build up; I have wondered about the risk to those who do not haul and inspect this at reasonable intervals. I have also found them in the center of the seacock barrels for the cockpit drain scuppers. There is virtually no sunlight in either of these places.

seacock barnacles
Ken.....just rub a little of the Moreys inside the seacock plug pass and up into the thruhull. Remember it is impervious to salt water.
