If your car won't start after a foggy night because your high voltage spark is leaking out "somewhere"???---Just spray WD-40 on the PLUGS/WIRES/DIST CAP/COIL TOWER & It'll START!

I sure never have, it runs out as a lubricant very quickly. As I recall there was a lot of ballyhoo about it when it appeared back in the '60s, I think it was developed by the Government, hence the name, maybe in connection with the space program.
Since all we had before that was 3-in-1 Oil, or maybe LiquidWrench, it seemed like a technological miracle at the time....seems like a waste now.
I have used Wd 40 to kill wasps. Works really well and does not leave a stain.
