Well that looks seriously cool to me, love the colours and the design is great, looks awesome, very nice work !!
Ian, why dont you try pactra?, its solvent based and I believe quite readily available, a quick google will sort you out.
Andy, as Ian says Jon has pretty much anything you will need, createx is great and cleans up real easy, I've heard nothing but praise about Jons other paints as well so cant go wrong.
Again nice to see you painting.
