I work on equipment, where there is a valve cap that gets cold and wet. the threads tend to rust, and make it impossible to remove the valve cap.
I've tried WD, PB Blaster (they rapidly evaporate) and a couple types of grease. What can be used to keep these threads from rusting?
Makes me wonder if Rectorseal #5 slow set is the choice? Marine grease? Dielectric grease? White lithium grease? . Christopher A. Young Learn more about Jesus
