I recently bought a used boat with Sunbrella top on the bridge that leaked everywhere. It didnt just drip it ran in. I thought I would have to replace the whole top. A West marine employee said to try 303 and I bought a gallon. I waited for a dry wind free day and applied the product. We didn't get any rain for days, but when we finally did, it was a 1/2 inch. No drips anywhere! Buy it, it is a super product. Great!

As expensive as this product is, it was disappointing to have the sprayer break on about the 10th pull. Similar issues are noted in other reviews, so I have to assume it is a recurring problem. I put the product in a windex bottle for application. Next time, I will apply with a brush. There is too much overspray. This was the same result with the few pumps I got out of the supplied bottle. At this point, I can't say if the product holds up to its claims. This is just to report the application frustrations.

                          The estimates for coverage on the bottle are not accurate; it requires almost twice as much when using on outdoor canvas type fabric. Also as you might guess its not effective if water is allowed to puddle in any way. so be sure your cover fits snugly and does not have areas that may well..it WILL leak...don't let wishful thinking fool you!

                                  Product is easy to apply and works well. I applied this same product on the canvas top for my boat and did not need to reapply for 2 years of constant abuse. I would and have recommended this product to friends at the marina.

                                  I have used the Formula 303 Fabric Guard for over 10 years on my cars convertible tops. I lived in New Jersey and parked my car while at work 5 days per week. The car was garaged at night. Twice a year I would totally clean the top then apply a good wet coating. I sold my last convertible that was 12 years old and the top was still in great condition! I latest car is a 2005 Honda S2000 convertible- top still looks great. I have also used it on upholstered car seats and carpets with excellent results. I'm going to now us it on the carpets in my power boat.

                                    Scrubbed down my full camper top to give it a good cleaning. Had it back on the same day and then out on the lake. It poured that night and the water came through the top as if it was not there. (sort of expected this) Went to West Marine the next day and the salesperson recommended the 303 High Tech Fabric Guard. Although higher in price than others, I have had good luck with other 303 products. I gave the top a quick cleaning again and let it dry and then applied the 303. 2 spray bottles worth on a full camper top on my 30 ft boat.We managed to go a full day without further rain so the product had good time to dry.
                                    Back out in the boat and rain again at night ................ WE WERE DRY !!!
                                    Easy to apply product, good coverage and minimal odour which did not seem to last too long at all. I will definately continue using this product on my boat camper top. Very happy with the results.
