I'm a bit late to this discussion but perhaps I can help some. First of
all, know that I'm not a fan of baking tapes as the initial approach to
Sticky Shed Syndrome (SSS). I have written an article that details the
problem and the approach that I usually take:
I would suggest checking out the article on lubricating audio tape as
well because the two are somewhat intertwined.
That said, I have been experimenting lately using a combination of short
term baking and then lubricating the tape for those tapes that simply
won't respond to the lubrication process that I use. The results are
very promising and I plan to add an update to my article on baking. The
procedure consists of baking for about 6 hours at 125 degrees F. and
lubricating the tape after it has returned to room temperature. So far,
I've tried this on AMPEX 406, 456, Scotch 226, 250 and Sony PR-150. The
results have been 100% playability. Because the whole process is
experimental, I have been lubricating and transferring ASAP after baking.
Know that all of this is anecdotal and therefore, you should proceed

A few of the tapes seem to have sticky shed (unfortunately, I do not know what brand of tape they are, nor exactly how old they are; they are approx.. 30-40 years old). I baked one of the tapes on a pancake at about 133 degrees F for about 4 hours, then let it cool overnight. However, most of the backing peeled off the tape. Some of the magnetized oxide side of the tape flaked off, too (luckily this was a duplicate tape, so it will be ok!). Since this was the result of my experiment, I am thinking that I maybe did something wrong. Also, I was using an Excalibur brand food dehydrator to bake the tape.
