Put this on the threads, it comes in little tubes at an auto parts store, it doesn't wash off. I put it on my tractor's three-point hitch turn buckles, a whole season of bush hoging rough stuff and it is still there.
All of my breech plugs and touch hole liners have a liberal coating of this stuff on the threads.
