I need warhammer 40k painting tips and techniques? I am making an imperial fists apocalypse army, ultramarines, white scars and another chapter not sure what plus a death korp apocalypse army. I want to make my armies look like they have been fighting for more than 9 years on a forge world with 9 years worth of damages, bullet holes in armour, grime, oil scratches and martian dust on all of my army can any one help me? I also want to recreate the engine burn and worn down ramps and greasy look of the guns as well as on the thunderhawk gunship on forge world. I'm not sure if you can include photos on this site. Can anybody give me advice?
