I use old fashioned strip type window calk for 2 thing that it works well for.
- I put a thin worm of it between my lock and barrel when installing the lock. It seals that gap perfectly and I rarely remove the lock when cleaning. Usually only before and after deer season. The inside of my locks stay corrosion free
-I carry some to stick on the seam between the frizzen and the barrel when hunting. This keeps the stray water drop from running into the pan through that crack when not using a cows knee.
