I use black Lightning Jets and I do paint them. I pain them silver. I try to do a good job and keep them looking nice. One of my buddies uses neon orange and just makes a few swirls. It doesn't look as good (of course, he doesn't look like he's wearing spats), but it accomplishes the same thing. I don't do it for underwater visibility, but so no one mistakes my fins for theirs. If my buddy needs me to have bright yellow fin so he can see me, we're too far apart. We need to get closer together, not change the color of our gear. I use Krylon Fusion and it does come off, but I expect to repaint them every 6 - 8 months, it's not a big deal. Fusion does last longer than the paint I used before Fusion became available.
