The SWT uses a spray on silicone seam sealer on their tarps. When I first got mine I could not tell that it was seam sealed. I contact Ed and he told me about the spray on seam sealer they use. After getting the tarp out in the sunlight I could see where the sealer had been applied. I didn't think that the spray on sealer performed that well but I have never had any leaks from the SWT. Ed also told me that I can use the silicone based spray sealer from WalMart to re-waterproof the seams every couple of years.
If you don't like the old, standard method of sealing seams with silicone caulk thinned with mineral spirits and a paint brush or syringe, then the spray on seam sealer may be a quick and easy option for you.
