Where it makes sense
Seam Grip SIL is the specialized choice when the surface to be sealed is silicone treated and the tent manufacturer approves a silicone sealant. GEAR AID specifies it for that coating family rather than for polyurethane-coated fabric. This distinction is more useful than comparing generic claims about waterproofing. A compatible product can address a small leaking seam; the wrong chemistry may leave a repair that does not adhere as intended. Check the tent component and its inner and outer coatings separately, because a fabric description can list multiple treatments. Keep the repair small, allow the stated cure, and check the result before returning the tent to regular use.
The tradeoff
Unsuitable for polyurethane-coated surfaces; coating identification comes first
