The end is near! I bit the bullet and hand cut the windows! It only took about 2 hours! I used .015 clear styrene. I trimmed each window to roughly the shape needed and used a multi-grit sanding stick to make the final fit. Each window is pressure fit but I still used a tiny amount of Testors Canopy Glue as insurance.
The last details are the windshield wipers, sun shade, and hand rails.
All that is left now is to plug in the decoder and go for a test drive!
