I use fresh balls for my under carriage. Works wonderfully. Goes on as liquid but dries to a silky powder.
I bought a tube on Amazon and tried it. Fresh Balls, when dry, is excellent. It's like graphite lube for your friction points.
However, the problem is that you have to let it dry. And dry good. Not easy when just getting out of the shower on a hot humid day. The only way I could get it to work properly was to dangle my junk in front of a fan for a while before suiting up. I deemed it impractical.
