Wood finishes (polyurethane) are meant for surfaces that are essentially immobile. Yes, wood moves- swells with heat and humidity changes. But it doesn't move like a piece of fabric moves: blowing in the wind, stretched between anchor points, rolled, folded & stuffed.
It is likely that you'll see cracks in the finish, and water will seep through. Flexible finishes (urethane, silicone) tend to work better on tarps rather than stiffer finishes.
And, a $6 tube of silicone properly thinned goes a looooong way if you want to waterproof your own stuff.
