Periodic reminder:
Many radios have black knobs with Center Slot "slits" which are also black and thereby all but impossible to see especially at night.
I use this stuff, super phosphorescent marker paint. Also specifically for use on gun sights. Is awesome. Small bottle will do dozens of applications. I use on all my gun sights and mobile black radio knobs with the center indicator.
I bought off of amazon.com but can get other places.
