Nice! As for the black webbing, how about trying this?
If you are using an acrylic paint for the red. Seal it up with a good clear coat like future, then use an enamel paint for the black wash. The thinner for the black paint will not eat into future so you can just dampen a rag in thinner and wipe off the excess paint with ease. I have done this before with not a problem in the world. It is a nice way to get recessed panels filled with color easily and quickly.
