Just for everyone's information, WD-40 is NOT a lubricant. The WD is short for Water Displacement. It is used to remove moisture, loosen rusted parts, protects against rust and corrosion, and it CLEANS most surfaces. You clean stuff with WD-40 (but NOT o-rings) and then put a lubricant on whatever that stuff is. It removes grease, tar, adhesives, and any lubricant that is on those precious o-rings that we all know about. If you put WD-40 on o-rings, it will clean them, but it will also dry them out and eventually ruin them, especially if you do not put silicone grease on them afterward. Use ONLY 100% silicone grease. You can find it at dive/scuba shops or at hardware stores in the plumbing section in either tubes or small, round, coloured plastic containers. If you want to clean your o-rings, just use a clean cloth and wipe them clean with it. Then use the above mentioned silicone grease to put a light coating on the rings. That's it. This simple process will keep your o-rings happy and your expensive illumination tools safe for many years. I hope this helps out anyone who was wanting to know about this. BTW: I have seen the post about teflon lubricants from radio shack... that sounds pretty good too, especially if Arc recommended it.
