I know some people recommend against it, but I'm a firm believer in dielectric grease on the contact and porcelain of the spark plugs. Since I've been using it, I've not split one boot or pulled the wire apart. I also use it on the distributor cap end of the wires. Just makes any disassembly much easier and safer. I've carefully looked at the plug wires, with the engine running, and in darkness and have not seen any arching. I've also never gotten bitten when adjusting the distributor for timing. I'm sold. My 2¢ worth.
