Realistic Tank Prisms...
Discovered by accident an easy way to color the small tank prisms that appear on most of the modern tanks...Abrams, Bradley, etc. Was coloring the inside of a Bradley range finder that's mounted on the turret using a magic marker because I thought it would look transparent (which it did). Then I tried it on the surface of those many little prisms that surround the hatch. Worked like a charm. I used a blue Sanford "Sharpie", extra fine point permanent marker. When dry it even has a kind of iridescence that looks quite realistic...just another one of those things where the wife yells, "Where the hell did those markers I had go?"
Love these "accidents"
