We are a little disappointed in the product. Our 10 year old Vaude tent was in the area during prolonged rain through water droplets and the sealing band broke up at the seams. The seams we got perfectly sealed after the removal of the remains of the sealing tape with SeamGrip. On the surfaces Granger Camping Fabsil was applied twice with a soft brush. The result: thick drops no longer get through, but if impinge from the outside fat droplets, for example, in a driving rain, then it comes under the weather skin at least partially as a fine spray finely atomized smoothly through to the sub-tent.. However, the majority of runs off well, but in longer-lasting, heavy rain of fine drizzle on the inside leads to moisture penetration. Normal Country Rain runs off against good since coming to nothing through. We try before the next season again with a treatment, there's 50% of the agent are left. Again we would not buy it though. Fabsil processing can be very good by the way, is also quite rewarding.
