Hello Maxida, and welcome to the 'Drome.
Rodens lozenge decals shouldn't be that tough to put on. They are printed as the real thing. So, when you want to apply, put them on as the real thing, i. e. chordwise.
First, paint the surface with some gloss paint. Cut the end of one strip at a slight angle to compensate for the taper of the wing, so that it fits the front edge middle and lies perpendicular down the wing. Cut it slightly longer than the wing is wide so that the aft part is going a little out from the wing trailing edge. Place the piece in warm water. After a little while, take it up to soak finish outside the water. Wet the surface of the wing with your finger. Carefully slide the decal in place, press out any air bubbles with a damp cloth and put some decal solvent on liberally. When almost dry, cut off the after part along the scalloped trailing edge with a very sharp knife.
Continue with the rest of the wing.
Worked for me. Some years ago I built some Roden OAW's. I used the lozenge supplied, though it's rather bluish (and I'm aware the rib tabes should probably have been blue.
Thanks,
Kofoed
