Talk About Static Cling...

..and, no, not from the clothes dryer! This is a frequent occurence to which I hope someone can give me a "why?" answer. Taking a clean LP, using a Zerostat gun and then applying GruvGlide, I supposedly would have eliminated static from the LP. After such treatment, the styrofoam test chip provided with the GruvGlide slides right off and no static appears present. After a one-side play, removing the record makes the hairs on my arms stand straight on end. So much static that if I don't "mute" the preamp, the built up charge will sometimes make the preamp "trip" and shut down as my arm passes in front of the cartridge. What is causing the static to build up so RAPIDLY, and what might I do to eliminate the problem. (MM cartridge, wall mount, no problem with cables crossing).
