Dave, you aren't referring to teflon thread tape are you? That stuff will not hold up to this, no way. IF I were gonna use teflon tape on that, I would order some clamp release tape from Bohning. Shrink tubing may be better..

You know what? I have a strip of the above mentioned tape at home. PM me your addy and I'll send it to you to try out if you want.

Oh, another thought. Would moleskin work??
