Hey 4Ssssss, what do you mean by "fray?" Fray sounds like threads are "blowing in the wind."

"Chafe" might be a better word? If so, I _believe_ that is normal wear and tear. My 986S has chafe where the folds are and I barely drive it, much less with the top down.

I'm fairly certain a few shots of silicone spray will slow the chafing process.
