powdered artists graphite? Great tip, thanks! But before I try it... I have about 20 lbs of powdered graphite on hand. Yes I know, way too much, but I get it free. I was wondering if this is the same stuff as you can buy in the automotive or hardware stores. I use it in artwork, but if I have a ton of the stuff at hand....why would I buy any to repair my PC? If you want to test it, a jug of Generals Pure Powdered Graphite is only about 8 bucks.
