Here's the sheet to tint the windows
Maybe a little darker than it should be but without an airbrush probably the best option. It's 0.23mm thick which makes it rigid enough. Have tried gluing some to scrap windows using different glues which left it foggy or streaky. So will attempt to just place it behind the kit glass and hope the lip in the frame holds it in place.
Using the kit glass as template cut and file the tinted plastic to shape
There is not a lot of tolerance. Too small and it just falls through, too wide and it won't fit.
Window on the left is clear, on the right is backed by the tint
Fit of the kit glass is so tight no glue is required. Takes a bit of patience to get it to fit without bending if too tight or falling through if too loose that one window took me over 30 minutes and a few bits of wasted sheet 😓
