I don't think salt water should be able to get to the gears in your reel in the first place, if so, there is a leak that should be pluged! But this grease should protect your gears as long as they are covered in a thin coating of grease! What I do on my reels, I put a few drops of oil, on the shaft that holds the spool,with the spool off and give it a light coating, that helps stop the water from getting!Also, after each outing in salt water, I rince off my reels, rods, lures with fresh water, helps prolong the life of your equipment!
