Part 3
After scratching my head for quite some time I’ve finally came up with a plan to paint and assemble the main parts of the passenger cabin and move forward on the whole plan to complete this model.
First paint and assemble the passenger benches (described in Part 2). Then dry fit and glue the cabin sides to the boarding area sides. That would create two main lateral sides. Mask and paint the sides to your desired color.
Then paint the cabin bulkheads/division from the boarding area, but don’t bother with the clear parts yet.
