Rallye gauge correct needle paint?

Enamels that use a solvent rather than aqueous carrier will tend to build a thinner film. If not starting from a clean metal base those seemed to be a better choice me.
FWIW Samples of Testors Fluorescent Orange and Red. Two coats on steel staples dipped in the jar. Metal was cleaned with acetone before dipping. Other cleaners would probably work just as well.
