nope, becuase you're dealing with conductivity and voltage. notice the bit about heat. when voltage is introduced, the free floating electron (or loss) results in heat. spray painting those connectors may result in a fire. also, even though 0.00 shows, all things have resistance, and since modern cards and chips on them are so sensitive, you may wind up doing permanent damage, and probably will. I would suggest that doing the board as suggest on the site itself is risky, spraying the sockets (AGP, PCI, CPU) would be utter computer suicide.
If you argue with an idiot he will drag you down to his level and beat you with experience.
