I am stubborn and when it comes to my hiking gear and clothes, I want to use it well and for a very long time because it’s expensive. I’ve had my tents for over 10 years and they work. However, the water seal started to fail after years of use and a fellow hiker suggested McNett Revivex Air Dry Water Repellent Spray. I took her advice and sprayed my tent with the repellent spray and it works! I always keep a bottle at my house in case I need to use it on something else. Maybe I can get another 10 years out of this tent.
