Sheet of clear acrylic, frosted one side (back side). Painted with a few quick passes of a matte black paint + primer on the ‘glossy’ side. (Plain old Rustoleum brand crud.)
Wanted to experiment see if my idea of lasering off custom backlit panels for joystick and throttle bases would work.
Backlighting in this image is nonuniform of course, and definitely proves I need thicker paint than just one coat. But I think the engraving comes out very clean, even for the total outlined lettering vs. single stroke (AEGIS logo).
