Great product that prolongs the life of your boats canvas.I clean my boats canvas top and spray it with the waterproofing every spring. It keeps the canvas flexible and waterproof for the entire boating season

Good stuff! I was lucky enough to put it on before a big inch and a half rain, it shed water like a duck's back. I can only hope that it will hold up for a good long while. Did a big boat cover and still had about a third of a gallon left. Worked good with a pump sprayer. Overall was a good buy.Whenever you see a solvent based formulation versus a water based one you know you are getting a better product. Water based products just don't last as long or soak into the material near as well.

Makes your cheaper purchases seem like sunbrella. Resists/repels water VERY well. We use on all of our outdoor patio furniture, boat cover etc. only complaint is the sprayer is leaky so you may want to use a different sprayer- or your hands will ALSO be water resistant

I really like this. I have to waterproof/winterize the horses blankets annually. This really worked well. I could apply it to about 5 blankets (one of my horse's is 7 feet (84") from chest to tail, my other horse fits a 72" blanket [6 feet]). It was the first product to last ALL winter on the 84" blanket. I was really happy not to have to reapply product after 2 winter storms. This was great to keep the horses dry & warm.

Good stuff easy to apply works as it should.

This product is amazing and worked so well on our canvas pop up camper. Huge rain storm came through when camping last weekend and nothing came through.

The media could not be loaded. ****Downgraded from 5 star to 3. See update below for the writeup on that.my boat is 16 years old and even though I have only had the boat for a year, based on the condition of the vinyl I can tell that the cockpit cover for it has been used religiously for all 16 of those years. The condition of the canvas had me convinced that I would need to order a new cockpit cover, but I decided to give this product a try to see if I could make the canvas functional again. While it looks old and weathered, it still functions to protect the vinyl from the sun, though very little functionality exists for rain protection. Now with this product I am positive I can stretch a few more years of functionality out of this cockpit cover before having to completely replace it.I took this video this evening since I was working on the boat when a rainstorm came out of nowhere. It is kinda dark, but you can see the water beading up on the canvas since it is under my bimini top and you can see the water just running off the canvas cover.Edit to add info:Coverage - 1 Gallon did my entire Bimini Top, Camper Extension Top, and 90% of the cockpit cover for my 24ft boat. I purchased another gallon since I ran out on the cockpit cover which was the piece that REALLY needed to be done. When I got the next gallon in I redid the entire cockpit cover and also the covers for my bimini top and camper top extension. I REALLY overdid the cockpit cover since it had seen the most sun damage over the course of the boats life. Even though I did 90% of the cockpit cover few days earlier, when the new gallon came in I REALLY saturated it a second time since I had plenty of waterproofing to work with.Before I took the video I assumed that the rain would just roll off as long as the canvas was taught when buttoned up, I was surprised when I got caught in the rain that even without being pulled taught the waterproofing did its job and made the water just roll off completely.I used a standard garden pump sprayer for application and did the bimini top while it was on the bimini top poles, I just set it up in my yard when I did it. The cockpit cover I draped over a couple small step ladders that I have, my garbage bin, and my recycle bin. This allowed me to hang it all out with nothing touching the ground. I started at the top of the step ladders and worked my way down each side so any overage would drip down and soak downwards to the sections that had yet to be done. This method worked well for me both times I did the cockpit cover.I hope all of this info is helpful to someone.New Canvas = hundreds/thousands of dollarsWaterproofing = less than 50 per gallonIt's a no brainer folks. Oh yeah, for those environmentally minded folks, and those who care WAY too much about how green their grass is, my grass was not affected by the chemicals.*******Edit 12/4/2015*****After surviving the season I have come by to downgrade my review to 3 stars. While I did not experience major issues with my canvas disintegrating like many reviewers mentioned I did notice that all of my seams started having issues. Granted my canvas was made in 2000, but it survived fairly well considering. After a couple times of removing my canvas cockpit cover I noticed that the threads in the seams started coming apart. My canvas is still functional but by the end of next season I will definitely need to get a new cockpit cover and bimini covers. It did a great job at re-waterproofing, but is not friendly on the stitching/seams. If you want to extend the life this will do the trick, but I think you may as well try the sunbrella approved stuff out there for a couple dollars more and hope that it works better on the stitching and doesn't compromise the integrity of the stitches.Again, for functionality 3 stars - compatibility with canvas and stitching that resulted in it deteriorating at a fast rate I had to knock it down a couple stars, but at the end of the day the waterproofing does actually work as advertised.

Applied one windy warm day by sponge after cleaning the surfaces and making sure they were dry. Next day, the sprinkler got the spa cover and sure enough, it beaded up nicely.Very easy to apply, covered a large swim spa cover as well as a 18 foot boat canvas cover.
