Hello, LM. The lozenge decal was very good to use and suffered no breakages whilst appyling it, unlike a lot of other Roden decal. I had the same experience when going my own Gotha. The crosses, on the other hand, were rather fragile.
I'm led to understand that the colours of the Roden night lozenge leave a lot to be desired but with this being such a monster I decided to use them, and not go for Aviattic, simply on the grounds of cost. I painted on a dilute wash of dark blue to dull down the rather bright light blue and I think this has improved it slightly.
