Given high wind exposure how would you set up your tarp. Outside of setting the tarp windward edge low to the ground. Would it be better to use lines with tensioner (the surgical rubber/sling shot tube type)? Does it make sense to "open" up a bit of the leeward side to prevent or reduce uplifting of the tarp?

Do you need to or should you reseal the seams of your silnylon tarp every season? Based on the thread about Permatex or the spray Silicone Water Guard as an alternate to Silnet it doesn't sound like much effort is required to apply the spray or Permatex. But if not necessary no point in resealing.
