Thanks all, I've had some trouble doing the wings and had to start all over.
By mistake I put some alcohol into the varnish when I finishing the wings the first time.
This made the 'magenta' bleed and they became reddish. I should have known because
I've had the same issue with the decals I'm printing myself!
It has nothing to do with the decals, they are great. They went down very well, in one piece on every wing!
I'm quite happy with the end result, being 'prototype' decals and all.
Cheers: Kent
