Thanks for the kind words guys.
Nexx, thanks for the input. I got the colours from a book called "Fleet Air Arm" by Squadron/Signal Publications. They've got numerous colour plates of FAA aircraft in similar extra dark sea grey/dark slate grey/sky schemes, although admittedly not this particular aircraft. They also show some colour photos on the back page which seem to tie in with the plates. I'd have to say the Corgi model's colours look wrong to me.
This Hasegawa plastic kit box seems to have similar colours too:

Math, I use Paint Shop Pro for skinning but this does have a psd converter built in. The trouble is the F6F files converted to psd format are huge, well over a 100mb in total and 36mb even when zipped. Each one also occupies around 800mb of system ram when loaded. This is because I stupidly went for 3072 res when creating them and they ran to 40-50 layers each. I'll have a look at doing a template in 1024 res and merging the layers down to 10-20 or so to make them more managable. I need to get my other skins done and off to HTC first though.
