I’m an airplane builder, and I’ve done this several times: For aircraft that have nonskid walkways on the wing, I use 600-grit wet/dry sandpaper. It’s easy to trim, and you can attach it with white glue. Thin and flat black, it’s easy to cut to size and has the right look. No masking or painting is required, and it’s easy to age or weather. I’m sure this technique could also be applied to other types of models.
