Sharpie Paint Pens are Not the same as a "Sharpie Marker"
The Paint Pens are filled with an Acrylic paint, and the Markers are filled with ink. (and the marker ink does bleed, big time)
If the brand name scares you,,,,,,go and Google " DecoColor" Opaque Paint Marker , those have a "shake pump" in them instead of the Sharpie "depress the tip pump" and those are available as Extra Fine,,,,,their Silver looks like Polished Steel when used on the active piston area of a nose gear.
