I’ve been using WD40 for years, but this is the first time using the penetrant. I liked the new spout and used it on seized rollers on our garage door,noticed immediate reduction in noise and vibration. Same results on storm door hinges. I’m guessing that the thinner viscosity of the penetrant vs. the regular WD40, helped reach some tight or inaccessible places.
