Painting the L4D2 block letters red in an ongoing effort to make this thing look cooler! I found a good bright red acrylic paint that matches the color used in the Left 4 Dead 2 logo. Looks like it's going to take a couple coats of paint to make it so the black 3D-printed plastic doesn't show through.
I'll also be adding a sticker on front with this image:
Hoping it turns out well!
