Many years ago Merc put out a grease in a tube that was the best I have ever encountered for prop shafts, driveshafts and any other surface you did not want water to get to - especially salt water. It came in a tube like large toothpaste, was colorless (sort of like vasaline) and was much thicker than the stuff I have seen on the shelf today. It was not for wheel bearings or grease guns. The only way you could clean you hands of it was with mineral spirits.<br /><br />Anybody know of a like product that is available today?
