Problem: We are about to stretch 6mil poly film
over a new 24'x72' greenhouse. I am afraid that I will "tear"
the 6mil poly film on a burr that may be on the 2" galvanized
steel hoops.

My thoughts are to "cover" the edge of the 2" hoops
that touch the 6mil poly with something like a run of
Duct-Tape.

Question: That type of tape (or other) would be best to use?
I am afraid that the Duct-Tape will dry out & become useless in
a short time. I am concerned that other tapes may have a chemical
reaction to the poly. 3M tech-support did not have a clue as to
what to use.

Please email me if you have an answer:-)

THANKS a million in advance!!!!
