I am getting ready to replace the panel in my Ventus B. Are there any
standard materials (especially the core) and recommended glass and
core thickness used to layup a new one?

This is a fixed panel, does not pop up when the canopy is opened.

I was thinking of using a 1/16" to 1/8" core of DIVINYCELL. So far
the thinest I can find is 1/8", is this too thick and will it handle
the compression of mounting screws through it?
