Insturment Cluster LED's

Proper needle paint is at ebay in a tiny bottle for about 7 dollars. Water base acrylic. Mixing ball in it. More than enough to do all your needles. Aluminum foil is the perfect mask for the screens. I dont use a brush. I have a big straight pin that my wife brought home from mattress factory. I load it with paint and lay it to the needle for flow transfer. The bottle is so shallow that my pin needs to be loaded a couple times to paint a large needle.
Most important "need to know" is about some needles construction, those with a flag opposite the pointer. On the backside of that flag is a dollop of material added for counter balance. Bend that flag at all and the stuff (whatever it is) will crack/fall off. This may not be an issue in simply painting the needle in place. Those vendors who offer screen decals, the videos that show removing needles to install decals, failed to mention/warn.
