Flying Wire Access Cover Tape

[wmorse]

Checking to see it someone has any idea on this. My Pitts has 1" round metal plugs to access back sides of flying/landing wires and has 3.5" clear round tape covering these caps to keep them in place. I don't know what kind of tape this is. It is clear or opaque, very sticky, the tape is slightly pliable and maybe 3-4 mils thick. If electrical was were clear and a bit less pliable, it would be a similar material.
I thought someone might know what is material is and where to find it. I just haven't been able to locate any such material.

Thanks in advance!
