As we all know carbon is electrically conductive (you've seen carbon arc lamps before). Of course the matrix resin alters the conductivity quite a lot, I was reading 35-90 Ohm's resistance across a 24" x 24" square pattern of #8 screws bolted into the inside carbon skins of my boat. This means that the conductivity whether along the fiber path or diagonally to it was pretty good. Mostly I was doing this to see if it was possible to use the skins as a ground plane for the SSB/HAM radios but it would apply to grounding the plane before filling the tanks. This doesn't do us with glass planes like the ES much good but it's a great point. I will probably run some 22 ga wire from the filler caps to the engine. Thanks for bringing it up. Dan Newland
