NightScreams blood is not a standard paint mix.
And yes it's a bit higher on price.
It's a 2 part style epoxy mixture.
It stays looking wet! Can be used indoors or out doors.
It's won't wash off or away.
And perfect for actor cloths, most paint when you wash turns lighter in color, a pinkish color.
Not this product, it stays blood red.
But yes a bit more in cost.
100.00 for a 1/2 gallon kit
Also available in a toxic uv green
And in our farting fatty puke color.

I've heard nothing but good things with pal nights blood.
