Back in the sixties, when some were teenagers, one of the guys decided 
to try the newfangled fiberglass resin. He figured how much gauze 
bandage it would take to spiral wrap eight bamboo spreaders for 20 
meters. Whatever it was, 978' , we went to half the drug stores in town, 
he would pull the store manager aside and whisper, “we need all the 
gauze you have, don't let anyone know and get more, there's going to be 
a run on the stuff.  We would go out with a couple of cases and go to 
the next store.

Didn't take that long, one spinning the pole and one keeping the gauze 
on an angle, for a couple of layers. A wrap of masking tape every few 
feet. Thing  was up for ten years and looked fine at takedown.

As I type, I'm looking at a roll of self adhesive “wall span” drywall 
joint tape, label says "fiberglass mesh to grip joint compound",17/8” x 
150 feet ?? Think the car repair or boat stuff comes in red, yellow, pink?
