Honestly due to the thick nature of plastidip I would avoid it on the tails. The added layer could cause the heat buildup inside the fixture to get to the point of melting the plastic. It happened to a friend of mine with very heavy vinyl on his.
If you are going to tint the tails I suggest either nightshade or smoked vinyl. If you or someone you know is good at vinyl application it is removable and if you don't, learning experience?
