Very Cool, and well done. I have not tried to bend any of this so, just throwing in my 2 cents. Even if you score the back side edges the ribs in the center will probably not want to bend. You could shape some epoxy or fiber resin. I would make wood trough the width of the trim, 1/2 fill with polyurethane caulk, spray wax, release agent on 18" length, press into mold Clamp, let it dry for a couple days. I have done similar molds for contour sanding blocks. What you have done looks really good, just the way it is, but if you get board / rained out on your renovation you could try something completely different...Ed.
