Does anyone have any tips for opening a stuck Light Cannon? I tried running hot water over it. It's been getting harder and harder to open (to break the initial pressure seal). I don't want to crack it trying to open it.

I cracked mine with a strap wrench http://www.hardwareworld.com/Rubber-Strap-Wrench-p10K9NI.aspx Mine had already flooded, so cracking the clear plastic under the rubber bezzel wasn't much of an added big deal. Underwater Kinetics actually replaced it under warranty, so I was only out the cost of shipping, and the time without my brightest light.NorthernShrinkage:Once you do get it open change the O-Ring beleive me I have had the same prob before and once it was changed it wasnt so Bad to open.
Try one of the rubber strap wrenchs easiest if one person holds it down flat (light) on the edge of a table while the other turns it.
