: I fixed the offended barrier, and now hold the strip out a bit
: while heating it. But it's not quite as elegant a method as
: holding the strip around the curve of the preceding strip, and
: exactly heating/bending the new strip.

: Any way to have it my way?

Get a piece of aluminum foil about a foot square. Fold it in half and set it over the form and your reease tape. Hopefully it will divert enough heat so your tape doesn't melt. f you end up stapling the strip in place and trap the foil, just tear it off neatly or let the excess stay there to protect the area when you heat the next strip. If you get enough epoxy leaking between the strips to glue the foil to the inside you can sand it away easily. It will be very obvious! It will certainly serve as a release layer even if the tape melts away, so you will not have your forms glued to your strips.
