FAR more important than this is that you must use something OTHER than
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
perfect temp control. That 130 degrees F temp is borderline melting
I've used 120-125, testing with the most accurate thermometers I could
my hands on. Check over a period of time as the oven will naturally
and need the heating element to come on again which can sometimes cause
temp to shoot over the 130 degree point. At that point tape starts to
and is ruined.

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