Re: [ARSCLIST] To bake or not to bake?

Most tapes that exhibit SSS, even if not severe, will stick to fingers 
if you try to pass a few inches between your fingertips. Some may have 
reservations about getting oils on the tape, but it's usually a quick 
and easy way to assess a tape's condition. Un-sticky tape will glide easily.
