303 ProductsMarine Fabric Guard – Water Repellent & Stain Shielding Fabric Spray, Safe for All Outdoor Upholstery, Simple & Easy to Use, Protectant Spray for Boats, 32oz

This product is absolutely the best to keep my jackets and full length waxed cotton duster ( which I wear in freezing rain) waterproofed. Will coat several articles fully with one bottle, and the sprayer works great . It usually can go several uses before needing respraying, every other product only lasted one use before needing to be fully sprayed again.It is strong smelling when applied, so use proper ventilation. After drying fully there is very minimal scent left.Highly recommended, I’m on my second purchase!

Great stuff for my old and neglected convertible top

THE GRACIOUS I'M SO SHOCKED!!! This is to make any fabric waterproof and when they said to lightly missed it one time and then repeat a second time it worked better than I thought there was actually way more in the bottle I thought it was going to run out cuz of all the things that I needed to waterproof but I think if I would have done it like I wanted to then there wouldn't been enough for all the products that I had to make them water resistant or waterproof to be more precise This is truly a remarkable product that does exactly what it claims to do

The product itself is a great product. For light rain, it will form small water drop in the fabric. For heavy rain, it is able to soak the fabric and this product is not able to prevent the water coming through. That is still ok. The bad thing about this product is that it is very easy to clog the spray bottle. Upon arrival, the bottle wasn’t able to spray. I had the content pour into a spare bottle I had and it was working fine. A couple weeks later when I tried to use the leftover from my spare bottle, it got clogged too.

303 is the only brand I've used so I can't fairly compare it, but I can say it works as good (if not better) than anything I could ask for. I do however have some tips I wish someone had warned me of:1)You'll use much more protectant than cleaner. One 16oz cleaner has thoroughly cleaned my top 3 times, whereas I needed almost all 16 of protectant to do one "decent" job.The second time I did it, I went crazy with the protectant. Used about twice as much; it actually looked like it would be pretty bad, but the results were spectacular. I'm sure there's a limit to how much can be used, but it's not less than 25oz. for a small car. Don't pour it on, but don't be cheap with the spray (you'll be glad).2)The instructions tell you this, but it bears clarification: You need at least 6hrs of DRY WARMTH for it to cure. They recommend a sunny day over 70 degrees, but the warmer and dryer it is the faster it'll work; curing can take 12hrs if conditions aren't ideal and where I live, there's lots of overnight condensation on less than really dry days. This will ruin your application (it will settle unevenly). Do NOT drive it while curing either or dirt will "glue" itself to your top.3)Speaking of glue, this stuff settles on your paint like some kind of super rubber cement; it'll rub off...eventually. The second time I did it I covered my paint with old bed sheets (saved me a LOT of clean up). It will wash off, but only with a stiff sponge and lots of elbow grease, so don't freak out about your paint, but save yourself the headache and cover up. Also low wind would be ideal (it is a spray) so maybe a garage would work (though outside worked fine for me).Do it right, and your top will look newer, have a deeper, richer color, and shear water like its made of Teflon. I always make sure to get a good coating before the winter comes to rip my top a hole. Great stuff.

I bought this product to restore my boat and jet ski covers. The covers usually are on my watercraft during the week and are exposed to direct sunlight rays most of the time, so they tend to fade out quickly. I combined the protector with a good fabric degreaser/cleaner that I used first. After letting the fabric dry thoroughly, I applied the fabric guard according to the instructions, using a microfiber cloth to wipe off the excess. It is important to be sure to get any excess fabric guard off of the item being treated. A microfiber cloth works well for this step. After applying the fabric guard, you could see a big difference, in the treated area of my watercraft covers, and the color was almost back to brand new. I would highly recommend this fabric guard for restoring faded out canvas covers. It works well and is not difficult to apply; in fact, I might start treating my covers on a monthly basis, just to keep my covers looking good. Oh, and the water repellency seems to be renewed also.

I rarely post one star, but i just don't like this.I had the Atsko Silicone Water-Guard 10.5 oz for one year to spray my 6 piece outdoor patio set, and i was very happy with the result and how long a 10.5OZ bottle lasted. recently i purchased a pair outdoor curtain 56X96 inches and i wanted to treat it with waterproofing spray. Because my Atsko Silicone Water-Guard 10.5 oz was out of stock, so i figured to give this a shot. there is nothing good about this spray and i have a list here,1. the spray trigger sucks! my hand gets Fatigue in a few second. it doesn't spray at an angle and very little product comes out.2. because it doesnt spray at an angle, you can not get the last bit of product out. worst thing is the sprayer can NOT be unscrewed after it is screw on. You just need to throw the last bit away.3.the consistency of the product is very thin and watery. a 32OZ bottle can NOT even spray a pair of curtain. i was able to do 1 and 1/2 leaving the last bit untreated. I had a 10oz before that treated a 270 sqt for 3 times in a year.4.when i rained, it repelled about 80% of water which means within 2 days, it had mold on my curtrain.since i used a whole bottle, so i can not return it anymore. I purchased 2 bottles of Kiwi Boot Protector 10 oz the following day, and used 2/3 of the first bottle to retreat the same 2 pairs of curtain. it perfomed fabulously and it was only about $8 per bottle.Do yourself a favor and skip this product. i was the worst $20 i have ever spent.
