Thanks for all the nice comments everyone.
Looking good mate!! The Thunderhawk is awesome as well. I haven't yet tried the new whites but I have heard that they provide much better coverage. That the case?
Ceramite white, is in one simple word 'awesome'. I still thin it down a bit, as a result I need about 3 good layers to get a decent white. My old technique required me to paint about 3 layers of fortress grey before painting 3 -4 layers of my white mix. Ceramite white is without doubt one of the best products GW have EVER bought out.
