Thanks very much chaps.
I've now got the re-spray done, with the model looking more like it should. Paints used were Humbrol enamels No.165 (satin) Medium Sea Grey, with a spot of Matt White, No.34, to produce a close resemblance to the 'Camouflage Grey', BS381C626 used on the actual aircraft. Other parts such as the speed brake, wing tanks and pylons have also been painted, ready for fitting later.
Next step, after some very light panel line work, is to give the model a coat of clear gloss, once the paint has fully hardened after around 24 hours, followed by the decals and detail painting, before proceeding with the rest of the construction stages.
Thanks once again for your interest and complimentary comments, and I hope to post another update tomorrow night
