Thanks for the comments guys.
Have got the whole plane painted in NMF- The upper surfaces will all be black, the underside being metal. Will get some photos up in the morning- will be tight enough to get finished, but should get it done.
Had a bit of a disaster this morning when the whole plane came out of the clamp I was using and landed with an almighty whack on the ground. Thankfully the only damage was the wing joint came free, but I have managed to get it all glued back together and repainted.
