I've seen the tutorials on superficial battle damage (scratches and drybrushing, as well as putting dirt and gore in the cracks) but does anyone know how to do the more extreme battle damage? Say large scratches, gouges, and dents where there are rents or where someone may have gotten shot, exploded on, or clawed by the covenant? Has anyone done that or have any ideas of how to go about it on pepakura armor? The stuff doesn't really dent, so that won't work just by hitting it. I'd like to make my armor look like it has character and is gouged up quite a bit from shrapnel flying around.
