I too had this problem until I learned what works for me. I get the adhesive backed day glow orange sheets. This
works great and you would not believe how well this shows up. I just do one stripe on the bottom of the wing about 3
in. wide. This is enough so I can tell oreintation. If the bottom of the wing is light colored like white I apply to dark
color (like dark blue) stripes and put the day glow stripe between them and there it is. Shows up great and looks pretty cool
