I was eager to install the port and starboard LEDs (breaking my written process, tsk..), and did so a bit too early so they've been in my way as I orient the model for my sanding the putty and masking the windows.  The cement I've been using doesn't bond to the LED plastic, so it's perfectly useless.  It takes about  four hours before it's totally dry, and I can remove the LED.  I think I will encase the thing in the cement - I don't want to use anything else for fear of damaging the LED or the hull.

     I have also masked the windows by putting some slits of tracing paper on the tape, then taping them in front of the window.  I'll have to watch how I paint the insides so as not to get paint between the paper and muck up the window.
