My fabric t-top was not shedding water like it used to so I treated it with 303 fabric guard which is recommended for Sunbrella fabric. Yesterday, I washed the fabric with 303 fabric cleaner, let it dry in the sun then applied the fabric protector in the sun and let it dry. It was really pretty easy, just had to wait for it to dry. Had the boat out today then rinsed it off when I got back. WOW the water ran off the t-top like a duck's back! I'm impressed. Not sure how long it will hold up, but right now I'm set for the summer rainy season. Thinking about treating my console and motor sunbrella covers next. Anyone else have experience with this product?
