BNA don't ship in, none of the regular shops will ship in. However you can do what I do and either get them direct from AK or find people on Ebay etc, I've just ordered 8 pots of AK RC and 16 bottles of Gunze as I couldn't get the colours here.
'Yea, Though I Fly Through the Valley of the Shadow of Death, I Shall Fear No Evil. For I am at 50,000 Feet and Climbing.'
The colour I'm after is RC104 Iraqi army desert sand I do have bottle of this I got from BNA I've use about a 1/3 of the doing brush test and then thin it out to use in my airbrush to spray on a test model I just not sure if I have enough to paint a fall model.
