303 Products (TOT030650) 303 High Tech Fabric Guard 32oz Trigger Sprayer

Very easy to use, long lasting, scentless. I used this on a western duster (cotton long coat) and it did not discolor the fabric or dye. It remained completely dry even in the heaviest of rains. The fabric was not stiff after the application dried. I did spray the entire inside and outside of the duster for added protection and used almost the entire bottle. It worked flawlessly. I am buying again for the next treatment. First one was applied in early 2019. Two years worth of solid rain protection, well worth the buy! The only flaw was about 3/4 of the way through application I had to pour the remaining contents into a new sprayer because the spray mechanism in the original bottle gave out. FINAL NOTE OF CAUTION: for product application AND while it is drying make sure you and the item you’re water proofing is in a VERY well ventilated area! Not a huge problem to complain about for a great product. Making my second purchase right now!!!

Used on my sunbrella patio umbrella last summer. Only applied one coat. It is not waterproof, it is water resistant. My umbrella is still clean, light rain rolls off the fabric. A long heavy rain will saturate and go through the fabric. I would buy again.

We are very pleased with the produt. We ordered 2 bottles and on both the sprayer does not work.

Used it to waterproof the leaking roof our our 2005 Mercedes convertible. It did stop the leak which was quite bothersome. The only downside i see is that to really get the roof covered two bottles are required.

Product as described.

I have used 303 products for years. Their convertible top sealant is the best. I use it on my 2002 Chrysler Prowler rag top. This is the original top and it still looks new. I apply the sealant with a new 2" paint brush. You get better coverage than spraying and don't have to worry about overspray getting on the windows or on painted surfaces. For the first application, I applied 2 coats. After that I apply 1 coat about every 10 or 12 months. When you pour a small amount of water on the top and it doesn't bead up and run off, it's time for another coat. Wash the top with 303 top cleaner, let it dry for a day, and then put on the sealant. Takes an hour or so and you're done.

Highly recommend for outdoor cushion, we use it for cleaning or to add a spray.

So first of all, the 303 Fabric Guard is probably the best tool to keep your convertible top looking great and making sure it stays in good shape. I have tried many products like it and find this one to be the BEST!It's not cheap but boy is it worth it...then why am I giving this 1 star? The nozzle simply didn't work rendering the bottle useless. You have to be very careful applying this stuff as it's difficult getting overstay off of windows and paint once dried. So I usually mask off the body of the car then spray on the product. That is not possible, when the sprayer doesn't function! I wish I was the only one this has happened to but apparently it's a common occurrence reading the reviews below.It's just not appropriate expecting someone who purchased this product to then having to go out and purchasing a sprayer nozzle separately (as I did). The 303 nozzle is designed to spray a very fine and light mist, also which is difficult to achieve with your dollar store or Walmart nozzles from an empty spray bottle.I hope this can be corrected as the product is too high class to sell such bottles with it.
