I'm gonna need all the help I can get on this one. I'm wanting to model and paint a space marine gored on the spikes of a dozer blade, but I'm not finding any good guides on painting/modelling blood and guts. What I'm gonna go for is a Marine impaled through the chest, with the lower half of his body missing, and ribbons of guts hanging out (hooray greenstuff). For painting the blood, it'd probably be something like blood red/ red gore mixed with some badab black and given a light gloss varnish coat.

I'd really appreciate any advice on this. Thanks!
