Could use some input.. Installed the single bed slide, nice and tight fit after taking a wire wheel/drill to the aluminum track prior to installation and clean up a bit of oxidation/corrosion. It slides ok but could be a little easier, and has me wondering what I could use to aid it. I have the usual grease guns, white lithium grease etc but figure that could get a bit messy.. I also have some powdered graphite I use for the Jeeps lock cylinders. Thinking this might be my best bet but wanted to ask those in the know. What do you guys/lady's recommend?
