Labelle products come very highly recommended in the model railroad community so I picked up some of their products including this 106 grease. I have used it on several of my N scale locomotives' worm gears and it works GREAT. It spreads quick yet it stays on the worm gear and doesn't immediately sling off like lighter weight oils and grease might. I picked this up in a kit with 102 and 107, and in combination with 106 they're all I need to maintain my HO and N scale locomotives.
