Thanks Mark, I appreciate it, I have managed to make a bit more progress.
I decided to invest in a set of masks for the roundels...
The masks are a thin latex and are tricky to position correctly... grrrrrr... but with a little perserverence...
With the masks in place I spayed a white undercoat figuring this would help with the red...

The MRP marking red looked a bit orange/terra cotta to me, but what do I know, I'm sure it will spray fine - all their other stuff does!
It sprayed beautifully, but still looked quite orange/terra cotta...

I sprayed more MRP which made the colour more dense, and oversprayed with a thin mix of MRP/Tamiya flat red about 10/90.

I think that this has got the red about right but to my eye could do with being a bit darker.
For now I will leave it alone and see I can get this rright with a bit of post shading and weathering.. if all else fails I can still use the decals !
Next time around I would - not spray the white back ground and paint over the black.
I did learn however that Tamiya seems to be able to co exist with MRP ( with care and test spraying needed first.
Next finish the markings and the camo!
