I used some Mylar that came with adhesive applied and the customer returned after one wing shed its top Mylar after he took the bird near redline! That's when I decided the process needed better "tooth"! Without sanding you are asking the adhesive to hold one smooth surface to another smooth surface.

Did you determine the transfer tape came off the Mylar and not the wing?

I don't see any inherent problem with adhesive adhering to a smooth surface, and
never had the tape come off the Mylar, but it has come off the glider. What
preparation do the transfer tape and/or Mylar manufacturers recommend?

I have encountered the same issue JJ described. As a consequence I always scuff seals as he described.
