Thanks very much once again chaps!
Chris, I was thinking more along the lines of doing mottle with brush techniques, as I did on the '190D.
Anyway, I was able to add some light panel lines, and a very small amount of feint dirtying, plus the begining of the exhaust stains, before giving the model a couple of coats of clear gloss, using Johnson's 'Klear' (Future).
I had a bit of a mishap as, not realising I had a smudge of grey paint on my hand, this transfered itself to the underside and trailing edge of one wing! In trying to carefully get it off, the base colour and mottle came away too, so I brush painted over the areas, touching-in the mottle/waves, using a 'damp brush' technique. It was then that I noticed a small brush-stroke of grey near the port upper wing root!
B*ll*cks! Must have been my stiff hands!
Not to worry, this will be taken care of when I do the light weathering and wear, both before, and after, applying the semi-matt clear finishing coat.
With the model put aside for now, it's time to attend to all the bits and pieces, and scratch-build a couple of items, such as the beam antenna for the lower fuselage, and tackle that tedious masking job on the long canopy.
Then, it's decal time.
Thanks again for your interest and compliments; the pics show the state of play to date.
