also further down the page it says it is a water displacer and thats where the letters "WD" come from. for a squeaky door hinge i would use a lubricant that wont wash away like WD-40, i would use white lithium spray grease. it is water proof and will not wash off and you will get years of use compared to WD-40. mark IN2TIME wrote: > >WD-40 is not a lubricant > > According to Jim and Tim - the Duct Tape Guys: > "If it isn't stuck and should be, use duct tape." > "If it is stuck and shouldn't be, use WD-40." > > I found it on the Internet, so it must be true! > http://www.octanecreative.com/WD40/
