As I fabricate the dashboard for the MOEPED 5, an electric bicycle
with ultracapacitor energy store, I require a tricky bend in Lexan.

I am wonder if five each 2500 F, 2.5 WVDC caps from that vehicle would
provide a suitable hot wire bend with a 14 gage stainless spoke as a
bending element.

Yes, the acrylic mounting plate is designed to prevent accidental
shorts. I have looked for plastic covers caps for the M6 socket head
cap terminal screws to no avail and may dip some with a product sold
in hardware stores.

You can melt a screwdriver with one of these at full charge, but on a
short, they don't vent the cyanogen unless they are in series and
there is an imblance causing a severe reverse charge. See previous
post. They are reverse polarity protected to some extent.
Unfortunately, Maxwell no longer serves documentation on these caps.
Also 10V is less than arc voltage in air (that's why cars had 12 volt
systems for so long) so that helps some for safety.
