Well - someone had to say it....
Tape Baking is a patented process. There was an in depth discussion on this
aspect of things on the Arsc list a while ago. It might be a good idea to
review it so you understand the risks you are taking.

FAR more important than this is that you must use something OTHER than your
gas kitchen oven. The heat needs to be dry heat and gas heat produces
water vapor. NOT good. An electric oven may work, but you need to have
perfect temp control. That 130 degrees F temp is borderline melting point.
I've used 120-125, testing with the most accurate thermometers I could get
my hands on. Check over a period of time as the oven will naturally cool
and need the heating element to come on again which can sometimes cause the
temp to shoot over the 130 degree point. At that point tape starts to curl
and is ruined.

If the tape didn't respond to baking, then it wasn't sticky shed that was
