Are most people painting themselves? Or is there somewhere I can get a blue?
Most do paint them themselves. I go for a nice bright Orange so I can see the pin when I drop it in the weeds. (ok good Metal-tech color as well) Quality rattle can is what I have used, with a primer. They get dinged up quick but easy to touch up if you want to.Are most people painting themselves?

Plastic inserts work well but are hard to find as you pointed out. I found heat shrink tubing works great. I've used heat shrink tubing in various widths, colors, and thickness to isolate, protect and insulate electrical wires from 4/0 to smaller gage wires. I also use it to protect and quiet just about anything. Simple to find at your local electrical parts or hardware store.Powder coat or rubberized tool dip. Both will scratch or gouge during use though I would think. Easiest would be to clean them up as best you can and rattle them. Then touch up is easy. There are plastic inserts for shackles that keep them from rattling but I can't find a link.
