a bit on topic...
Since I don't know what the inside of your build looks like i'll share what is working in our DIY setup.
We went soft walls on all surfaces rather than panels and it is working great five years after install.
Here are two shots of the areas you mention. My wife did all the detail work and you don't even notice the seams it is that nice:
Slider:
And the rear doors:
Under all areas are bubblefoil/reflectix all applied with 3m 77 adhesive and covered with marine grade Hull Liner.
Best wishes on the project,
Thom
