yep the paint stuck it to the pin. Doesn't take much the gauge is really really weak.
I painted my old cluster's needles a long time back. even after I let the needles dry for two days the needle still stuck to the pin.
I put a tiny dab of super glue on the spot where it rests. (with it held off the pin obviously) since super glue drys fast, it created a hard layer to keep the needle from sticking again.
