Labelle products come highly recommended in the model railroad community so I picked up this kit. While I have not used 107 yet I have used 102 and 106 extensively and the results have been fantastic. I've been using 106 on worm gears and 102 on truck drive gears and the products are slick yet they stay where you put them and don't run or sling all over the place. I imagine there are many other uses for these oils and grease but so far I've only used them on my N and HO scale locomotives where they have been amazing. I highly recommend them.
