An excellent result for such an early test.

Suggestion - Print the sections from scans of the front of the backglass. Select the RED sections, and print the red sections (laser printer or similar) on A4 transarency. That way, you might be able to slot the A4 sheets behind the backglass trim ?

Yeah - this could go anywhere Nino.
I was thinking about some other , stiffer material.

Happy to see that 'an effort' WILL at least achieve some result.....now I can think it through properly.
