I'm trying my hand at it now. Sun shields will probably fit inside the
plexi windows and be something stiff like that honeycomb signboard cut to
shape and covered with aluminum foil and then maybe a film of cellophane or
clingwrap to keep from scratching the soft plexiglas windows.

For the glareshield over the panel, I'm making a pattern from cereal box
cardboard, then cutting 016 aluminum to fit, then covering it with 1/2"
thick foam and then maybe leather or naugahyde, or whatever. How about
some ideas here. And thank you for your support.

Nice article about sunshields at Avweb, interview with Kennon on how they do
theirs and what they recommend and why.
