i hardly use it because i never go swimming with my lights but for such cases, water-proofing, the best of the best "lube" is silicone grease. Both on the threads and the o-rings. Silicone grease is thick (very thick!) and sticky. professional divers use it too to water-proof their equipment.I keep all my o rings well lubed and threads cleaned with light lube.
i have it, works well to seal your flashlight threads and o-rings.
