Thanks chaps,
Back to it with this one.
Now painted the airframe. The upper surfaces were painted first, using Tamiya Light Ghost Grey from a rattle can. This sprays very nicely if you give lights coats until an even finish is obtained. When fully dry, the uppers were masked off and a couple coats of Intermediate Blue were sprayed on. I mixed my own shade using Tamiya Middle Blue, White, and some Tamiya Clear. My mix was roughly 30% blue, 60% White, 10% Clear thinned appropriately using Mr Hobby Levelling Thinners. Because of the Clear being added to the paint mix, I ended up with a smooth semi gloss finish.
The undercarriage bays were masked and given a blast of Tamiya White.
When I painted the airframe I painted the main undercarriage legs the same under surface colour, only to find an unnoticed seam line running the length of each leg. This was filled and sanded and will need repainting before final assembly.
Some pictures follow:-
Thanks for looking, back soon.

Plenty to keep you busy, or is that 'out of trouble'?
Watching with interest.

The 'wanderer' returns..........

It's on the way, just waiting for some more refuges.

Could be a very interesting diorama in the offing with one of your great Tank models.
You could allocate names to the refugee's based on club member's which would be interesting.

Thanks Bob - its a lot of holes in some mud - about my level I think. 
Also not a figure in sight, so Howard can't make comments about the face painting - hohhohohohho

From 'Engineer' to 'Mud Mover'..........Impressive skill change, hohohoho.

Very Nice Bob.
Backdrop makes it look real again.

History before our very eyes.
Nice work Zak.

A little update.
Today I removed the masking from the nose sensor turret. I then sanded back the clear plastic part to ensure it sat flush with the turret sensor recess. I then gently polished the clear part with gradual finer grades of sanding stick, until I reached the polishing stage (White side of the polishing stick). Within a short time a nice clear glass like surface was achieved.
I also added the missing radome's and ariels off the upper surface.
Next job will be painting the upper surfaces. Thanks for looking,
Kevin
