White undercoat before applying fluorescence on black latex?

[Grovebough]

Hey! I want to apply fluorescent paint on the claws of these latex gloves. I've never applied fluorescence on black before and I get the feeling that maybe it's a good idea to first apply a white undercoat on the claws in order to increase the fluorescent effect. Does this make any sense and is it a good idea?

It does make sense. Usually these paints need a white base underneath to work.
At least the ones I´ve used.
