Thanks for chiming in on this Hangnout. Those are great recommendations.
The only real possible point of water infiltration on the cuben tarp is the 4 panel pull outs. I assume that is what OMS is referring to. We have recently started using a small amount of seam grip on the panel pull outs. The perimeter pullouts might also weep though but they are on the perimeter so we do not seal them. I suppose you could seam seal them though.
