Question: I have vinyl hot tub cover that's getting sun damaged. I was wondering if this product could extend its life any ?
Document: Out Canoe Trip group needed to recoat our 12' x 20' nylon tarps that were over 20 years old.This product worked great. Was easy to apply with a 1 gallon sprayer and only took about 10 minutesper tarp. The coating will extend the life of these tarps for another 5 years at least.
I've used it on 10 yr old sunbrella material that has been in the FL sun every day of it's life.Water still beads a year after applying it on this material
I've used Star Brite Waterproof Spray with PTEF twice in recent years and this product does exactly what I expected. I sprayed my fabric boat cover with Star Brite using my yard sprayer. I laid the cover on a tarp and the entire spraying process took about 30 minutes. Once it dried, it was like a new cover. Now when it rains, the rain runs off like the cover is made of vinyl.
I did the same treatment to a tent with 5-star results. Undiluted, it still sprays well from an old spraybottle without too much waste if you're careful. Give it time to DRY! After clothes dry outdoors for at least a full day and lose their odor, a short tumble in a hot dryer while turned inside-out seems to finish the job and bring them to life. On cottons and heavier fabrics, it works, but expect 4-star results after 2 coats.
I bought a new gazebo for my back yard, and was looking for something to prolong the life of the canopy.I loaded this into my sprayer and saturated the canopy, and now you can watch the rain slide right off.The liquid had a strong odor, but there was no trace once it had dried a few hours later.
I feel this product did the job I wonted it for my boat cover.The product went on with little problems.
I applied Star Brite to my boat cover approx. 2 weeks ago. We have had received 6"-7" of rain since and the product, thus far, seems to doing an excellent job.
I used this product on my boat cover and also on my canvas top on my convertible. Before applying the spray I had problems with dampness and leaking on my boat. After applying Star brite waterproof spray the water beads on the cover and the boat stays dry. I have tried other sealers and this one has performed the best.
We bought the recommended product for our sunbrella and wondered what we were doing wrong. I did not waterproof our boat canvas. No matter how we applied it or how many times, water did not bead up and run off. On coating with Starbrite a year with any application method from sponge to brush to spray and it is  done perfect. Not just the boat cockpit cover, Bimini and Bimini boot, but our deck umbrella and other miscellaneous items. This is the best.
My Sunbrella cockpit cover has never been restored (from 1998). Washed the cover first with Dawn dish soap using a soft mop like brush. Let it dry and sprayed with this product. Sprayed until the cover was completely saturated. When dry, the cover now feels soft and beads water like it was new. This was more than enough for my cover (23' boat) as I have about 1/4 left.
Answer: yes
