I've been lazy. Should have finished this months ago, but I got distracted by work an other pet projects. I have the gesso, the cardboard and the sandpaper, but I need to order more of the retroreflective paint, and I might need more primer. I recently used up a lot of primer painting DIY storage tubes for a couple of shotgun microphones. I think I'll order three cans, one white, one grey and one black.
