CSI used to have racks to use with their fluid beds but I don't see them anymore. They held 100-250 jigs or blades for dipping.

I see the spray option now, didn't see if before, sorry about that.

Hanging the blades is gonna work better I think. Paper clips placed in those jig holders so you can hang them upside down would work wonder. I have used paper clips for years to paint my blades although I am still painting one at a time.

Still remember to build a small paint box so you don't have powder paint repainting everything where you are working. Let us know how it works if you go with the airbrush option. It would save me a ton of time to painting my spinner bodies and blades.
