I managed to spray my new eldar this evening due to a lack of hockey practice and it struck me how useless GW spray is with metal models. You pay £8 for a can for a start. Sure, it will happily undercoat any plastic model you set it upon, but having spent half an hour outside freezing my fingers off (I love you, Scottish weather), to be rewarded with paint that just seeps into the creases I'm beginning to wonder if it's the best way to undercoat. Hand undercoating takes to long and I'm worried about using my local DIY stores stuff because of its thickness. Any ideas from people would be a great help i.e. what sort of spray do you use?
