Wing Walkways
My chosen decal set does include wing walk decals but these are black and long and are in my experience always a nuisance to place realistically. I decided from the off to mask and spray mine. After masking I used small dabs of Maskol to represent wear and tear before spraying the lines NATO Black. Once the tap is removed and Maskol rubbed off the result is to my eyes better than decals.
Whilst I am in this area though I have included a shot of the upper wing star and bar which on the real aircraft has a large part of the inboard element of the bar worn away. I replicated this by taking a piece of Sellotape to the decal and removing quickly. The result is as you see.
