The sliding strip on the auto gear selector on the old SD1 Rover didn't survive the oven which baked the new paint on. It's well and truly frazzled.
It's approx 4" x 12" and somewhat under 1mm thick. It's black in the middle, but with translucent green at either side to allow the bulbs beneath to illuminate the gear you're in. In other words, it slides in a housing controlled by the gear leaver.
I could make and print out something similar on the inkjet. But don't think it would survive for long. Would a laser print be more robust? (Both overhead projection transparencies)
Or should I simply use some paint? If so which sort, and what kind of transparent sheet?
