I would recommend using something other than aluminum for the
glaresheild unless the aluminum is rivited very well to the instrument
panel, and has the edge rolled. A sharp sheet of aluminum is like a
knife if it ever gets forced back into the cockpit...
Putting a slight curvature in the panel to make it deform upwards
rather than trying to come back would also help.

Good point, but if it's riveted to the panel that makes it tough to
get behind the panel without being an inverted contortionist. A few
screws going into L-brackets on the backside of the panel should
secure it.

Think long and hard about how much of a guillotine blade you want
extending over the panel. It seems like a nice idea to shade the
panel, but you could have a situation where part of the panel is in
bright sun, and some is in deep shade from the overhang. Might make
it hard to read the instruments at a critical moment.
