It may well be that this is old hat to you all but for me it is a new discovery.  I love my Cooks custom sewing tarp but have always been worried during a wind of doing damage to it. It is such a big sail and the stress to the ties severe. Went down to the local hardware and bought some American made shock cord 3/8 x 14" for all four corners and to rig it lashed each end of the shock cord  with 440 cord loops and then frapped the 440 cord to the shock cord with some nylon cord. That done I doped the ends of the shock cord and the nylon frapping with that very liquid super glue. I made sure that the exposed ends of the rubber bands got plenty of glue to for sure hold them in place.
Well I tested it out the next day (20-25 mph wind) and it worked just like I hoped it would. The wind could never get a solid hit on it, and a side effect was that sound of flutter, flutter, flutter that the wind makes playing with an edge was gone. It's reasonable to think that the tent pegs used to put it up ought to stay in the ground better too.
Best Wishes, Rob
