haha, I remember a veryyyyy angry modeler that came after me once,,,,,,seems he was upset with me for advising him to use a Sharpie Paint Marker on his red landing gear door edges,,,,he used a Red Sharpie instead of a Red Sharpie Paint Marker
turned a shade of pink under the clear Future coat, I believe (all I remember is that he used an Acrylic clear of some kind)
since buying and trying those Paint Markers,,,,,I have gone back to using a small paint brush again,,,,,after you have the markers for a while,,,they basically turn into a weird "paint pump device that you need to brush paint anyway",,,,might as well skip that step and just use the paint from a bottle, and it is far cheaper per bottle than it is per Paint Marker
there is one good use for Markers,,,,,find some of the superfine Permanent markers, or Sharpie metallics,,,,,they do work great for touching up metallic "oops" spots if you see one at the last minute, after you thought the model was all "done and great" (at least, that is always when I see the oops on mine)
I would worry a LOT about bleed through with Acrylics,,,,,,it might be worth a try with Enamel paint,,,,,don't know
