Waterproofing two tents
I purchased the Nikwax Tent and Gear Waterproofing after researching tent waterproofing online. The Nikwax was very easy to use, I like the fact that it's a water-based product. I was able to set my tents up inside the house and treat them inside since I have plenty of extra space. I was able to treat a new Marmot 3-person tent and a well-used REI 2-person tent with a 32 oz. bottle. I used several coats on the REI tent since it's 12 years old. I took the Marmot out last weekend, it didn't rain, but I am sure the waterproofing will get tested in the near future.

Works great
Purchased the 500ml bottle to weatherproof a one man tent fly. I applied two coats and used 3/4 of the bottle. Easy to apply and works great. Eliminated the fly from wetting through to the tent fabric.

great stuff
bought the 500ml bottle for weatherproofing a canopy cover on the patio 10 ft x 10 ft. I wish I had bought a larger bottle. Still it worked great . Easy to use and effective at keeping us and our chairs dry. Thanks, Fast shipping too!

Highly recommended for Tents!
Three weeks ago, I purchased a brand new Coleman Kohna 8 Tent. Having gotten extremely tired of numerous nylon tents degrading and eventually shredded by UV and a slight breeze, I wanted to protect this one. I Googled and found this product here on Altrec. With it being an 8 person Tent, I ordered 2 500 Ml bottles of it. All I was really interested in was the UV Protection. As any good owner of a new tent, I set it up and seam sealed it. (All new tents need to be seam sealed.) I figured I'd leave it up until the Nikwax Tent and Gear Proof got here. It turned out to be a very rainy week. In that rainy week, I learned that the tent's waterproofing wasn't all that great. The seams were watertight but the fabric wasn't. It didn't exactly leak but it did soak through in places making the fabric darker where water had soaked in and small rivlets of water ran along it inside. The Nikwax arrived and the weather broke. I followed the directions on the bottle and treated all of the exposed areas of the tent and let it dry. The next day it poured out. And the day after that. And the day after that. And a driving, heavy, windblown rain came down the day after that! The tent was bone dry inside with no indication of water infiltration into the fabric whatsoever. If that isn't a test I don't know what is. If the UV protection is as good as the Water protection, I'm going to be a VERY happy camper. Literally. Nope, the stuff ain't cheap but if you value your gear and a nice, comfortable, dry place to stay in the Outdoors, my opinion is that it's worth every penny for old or new gear. I wish I'd found this stuff years ago! On a side note, Coleman obviously ain't what it used to be. There's just a bit of sadness to be had there.

another great product from nikwax
This stuff works great, just like all the products I have purchased so far from nikwax. I use this product on a variety of camping gear, and it has replenished the water barrier successfully on each and every one of those items.
