I too use a dry molybdenum spray to lube slide, jacks, and anything exposed to the environment. The spray goes on wet (the carrier), and when it dries it leaves the molybdenum coating. If you get on your skin it must wear-off, on your clothes-it's permanent, on metal it lasts for months. It is black so you know by sight when it wears off and it's time to re-spray.
"get that dirty". Oil or grease attracts dirt and road grit. Together they make a crude grinding compound.
