Today I finished applying primer to the dome panels. A couple of heavy coats conceals the gray primer beneath. Hopefully the weather will cooperate and I can start the actual painting very soon.
On another note, the red LED in the front PSI isn't as bright as I'd like it to be. I experimented with a 3000mcd red LED. If I can figure out the resistor needed for my current PSI circuit, I will probably go with this one.
