I used to have a boat with twin outboards I used in saltwater. After I had a huge problem taking the lower unit apart because of corrosion between the SS screws and the aluminum lower unit housing I put liquid Permatex gasket cement on all the screws when I put it back together and years later had no problem taking it apart again. Maybe a small dab of gasket cement on the threads of a shotgun wouldn't be a bad idea to help with future servicing. As it is, I always put a dab of Permatex Anti-seize (sparkplug) Lubricant on the threads of the percussion nipples when I'm done servicing and cleaning my muzzle loaders. I also use the stuff on the choke tubes on my Remington 870 rainy day gun and have never had things stick together later.
