Thanks for the tip. I helped my son work on his POS VW bus last
weekend, and we needed to remove a number of very rusted screws. The
philips head screwdriver kept torquing out and buggering the screw, so
I tried your valve grinding compound trick, and it worked great.
thanks again,
tom

they use a bit of valve grinding compound on the tip of the screwdriver to
reduce cam out. Never tried it myself.
