I recently purchased a surefire KL1. It is an earlier model that appears to have 3 separate parts which are either threaded or pressed together. It appears the inside piece had a gasket or rubber washer which is partly missing. Looks to me like water could get inside of the head itself. I had thought about putting a small ring of epoxy around the joint where the seal is missing but I don't want to ruin it so I couldn't resell it if I decided to. I guess my question is: Would Surefires warranty cover this?? I'll call them myself on Monday but wanted your thoughts since it's Saturday evening. Thanks for your input!!!
