I too run the BassKhang’s and SD, but I still sand both near the tips to get the diameter I’m after. To repaint, I use Krylon as a base coat (white for the tip), then after a day or two of dry time, I hit with Testors Pactra in either Fluorescent Orange (preferred) or Fluorescent Green, 2 coats. I will then tape off that section after it has dried, then I hit the rest of the blank with whatever color I want it to be.
I’ve been playing around with different tip colors, and how much of the tip to paint. I will do at least to the first guide, but usually the second (so around 5″ from the tip). I prefer the orange, but also use green, yellow, and pink. I will also use the same color thread as the tip color for the guides in that area to make it all come together. Also, when adding my first coat of finish to the guides in the colored tip area, I will add a drop or two of Testors paint to the epoxy, along with some glow-in-the-dark pigment.
