just dilute the white glue by about 50% and tear all the flat edges off the paper , and try to find a good pattern for the paper , dont use quited style LOL , and apply signle plys at random , i did stuff his torso so the paper would not rip as i tapped it in place with a soft brush , do it randomly and let layers dry before adding , the muscle is twisted toilet paper with torn sheets laid over it .
as far as painting , Tamiya has a great series of clear colors ,Red, Green ,Smoke and yellow , mixing these can produce some really effective gooey ,bloody nasty pus dripping fun !! and the best part is , if your unhappy with the results , just soak in water ,remove and start over !
