Hi Marie:

Even with quarter-inch reels? I thought the 24 hours and even 12 hours was for 2-inch reels, the 
theory being it takes longer to bake out the center of the tape pack??

The last time I had to bake reels, I think 2 years ago, it was 456 quarter-inch. I did  the 8-8 hour 
cycle and didn't get any residue. But soon before that, I had two reels of Scotch 227 (1-mil) that 
required 12 and 12 hours (they were still sticky at 8 and 8).
