Ok update on ongoing progress, the reflection Mylar film is glued to the petals. I am disappointed that in pictures it looks like tin foil, but this is because the Mylar has zero give to stretch into place to smooth and wrinkles.  I think this would work much better with reflective window film because it can be formed and has ah adhesive layer as well. Anyways functionally the wrinkles should not make any difference at all.
