A must to keep water/moisture out and insure aluminum (or other metal) threads are kept clean and free of contaminants

My lengthy Headline says it all. A definite must for any flashlight or "Go-Bag".
  • Just enough grease in a hard small case... goes a long way.
  • None

Does the job!

First I wasn't caught completely off guard by the size of the container however; it was still smaller than I thought it would be. Measured in grams not ounces or in this case fraction of an ounce. The container inside is only about .9 inch across at the mouth and just under .7 inch deep! Outside is right at 1 1/4 inch across and only .770 inch tall!! So now you know what to expect. That aside it appears to be a top notch lubricant for flashlight threads. I cleaned up every flashlight I own about 6 with metal threads and with a tooth pick scrapped the lid of the container to get some silicone on it and was able to sufficiently lubricate all 6 flashlights off of the tiny amount stuck inside of the lid. I have no idea what I am going to do with the jar of silicone now, maybe set up a business cleaning and lubricating flashlight threads! Ha! Seriously buy this when you are young and a "container" should last for the rest of your lifetime.
  • I does the JOB and enough product to do thousands of flashlights in my book.
  • The lid does not have an arrow on it or in any other way indicate the lid screws on / off, (the packaging is silent on that too) It looked like a "snap on" to start with until I pried it off and saw threads. Well since there was plenty of lubricant on the threads they were not damaged and I ADDED an arrow and the word off to the top of the container since I will probably forget by the time it is needed again. Geees! Come on China, nice Nitecore, silicone grease, and SG7 imprinted on the lid how about a little arrow and the word "off" on the lid also for those of us who are container challenged?
