Decided to re-mask the rear baggage compartment - I was not happy with how the paper masking of this area was not flat enough to promote good even paint coverage. Used cardboard to create a panel which I placed against the inside of the rear baggage area, and used safety wire to hold the cardboard against the rear of the bulkhead.
Received the Chicago Tools HVLP sprayer, looked it over and read the warnings/instructions/hold harnelss info...
I might re-mask other areas as I make final decision about what I want painted inside the airframe.
