FWIW WD40 is neither a lubricant nor a penetrant. It is a liquid designed to fill gas tanks of vehicals that where shipped overseas. Its something that wont hurt a fuel system and will displace gasoline fumes and sea air. I once took my M16 for an outing with only WD40 to lubricate the gas rings on the bolt. Fried those suckers.
