Not sure if I am in the right forum.... Hope so. I have put together a pulley system that consists of two steel 3 inch loops. One is looped inside the other, so there is friction when they rub against each other under stress (twisting-turning metal on metal). Does anyone make any type of spray-on lube that will harden so that its lubricating properties will last for some time. I realize I could use grease but it would be pretty messy for what I need. Also, something like WD40 will probably evaporate off pretty quick or drip off. An ideal situation would be something in a spray can like teflon that would harden when sprayed on and would last for months.... don't know if such a thing exists.
-Thanks for any help.
