One of these days I'll try zapping mine. If the thing bursts into flames I'd have an excuse to buy another.
I wonder if there would be any benefit to making the zapping part of the scheduled maintenance. Might it be better to wait till it is needed or would regularly zapping--say, every 6k or so miles--be advisable. I suppose it would depend on what exactly is happening.
Is the material really just carbon? Anybody know other applications where this material is used? Knowing that might shed further light on the problem.
