Used this on my car's convertible top and it really exceeded my expectations. It's a little messy to apply and the spray does float around a bit, but the end result is excellent. Just spray the fabric until completely wet and let it dry. Didn't change the appearance of my dark brown top at all. I can't even tell it's there until it rains or I wash the car. But the water beads up as if the fabric has a fresh coat of a good polymer wax. The factory treatment was pretty much gone in about 6 months. The 303 product has only been on for two and a half months, but shows no signs of fading. I'll try to remember to update later with regards to longevity. I used about half the 32 oz bottle to treat the top on a two seater. So, if I'm doing this twice a year, it may get to be a bit pricey, but way cheaper than a new top in eight years.If you use this on a car top, be sure to put old bed sheets or something similar on the bodywork, and cover windows and glass as best you can. The overspray does come off, but it's a bit of work.
