I agree wholeheartedly, and would take it a step further. Not only is WD-40 a bad lubricant, I think it actually causes damage, because it is very effective in washing away whatever traces of proper lubricant might have been lingering in the joint, leaving a dry joint after the WD-40 runs off or evaporates. I've learned this through experience. I never spray WD-40 on moving parts, unless I intend to remove the WD-40 and relubricate them afterwards, or don't care. I use synthetic grease on my door hinges, applied with a coffee stirrer, because my grease gun wouldn't quite reach. I love WD-40. It's great as a cleaner, a lubricant for cutting tools, and as a loosener of seized bolts. It's a terrible lubricant for wear points. --- In dmcnews@xxxx, "content22207" <brobertson@xxxx> wrote: > WD-40 isn't viscous enough to be used as a serious lubricant.
