The flettner strip material that came with my kit was so warped that I
didn't use it and instead made my own out of some spruce. I painted some
epoxy on the installed spruce and that seems pretty hard. It's hard to
imagine getting any glass to wrap around a more than 90-degree edge without
vacume bagging or something.

Tony,
I did as Nigel, bought some thin fibreglass material from the hobby shop.
You will never
get the regular bid around the sharp edges unless you make some kind
of clamping device.
