Pigs Might Fly South’s Scratch Gel and Wound Filler are both based on the original formulation of the Dark venous Nick Dudman blood, but with an additive that creates a thick, congealed effect.

The Scratch Gel is the least congealed of the two products and is ideal for applying direct to skin/prosthetics to create a grazed effect or to apply at the edges of a wound; the Wound Filler is more congealed than the Scratch Gel and can be used to represent flesh or deeper wounds.

Both products are syrup based and will therefore gradually lose some of the viscosity as they warm up on an actor’s skin; they can also be mixed with the dark venous blood for use as clotting blood.
