Hey guys, this is going to be gross but it shows you the power of this product. I don't recommend you do this on your top until you do some testing though. You city people might want to move on to next post.

I used RollOff to clean my boat top which had been used by a predatory crow for his killing/eating roost! I am sure you get the picture here. Snakes, a rat, other birds all taken to my boat which hangs in my boat house for the final disposition. Blood, guts, gore, etc. I eventually ran the worst crow off by peppering him with some rat shot but what a mess left. Tried various cleaners with no real result. Remember whats there! The stains, etc. Yeck. Anyway, while detailing my car using products from the Roadster Kit from Classic Motoring I noticed the RollOff. Tried it on the Boat top by wetting the top first then spraying on the Roll Off full strength and scrubbing with a brush. First round did really well, second round and I have like a new boat top. I am IMPRESSED and that doesn't happen easily. This top is 16 years old and has been restiched several times. It looks great - better than in the last 10 years at least. Also used the product on the stains on the fiberglass and they also came out. Anyway, thought you might want to read this testimonial. But on a black S2000 convertible top my advice is go slow and dilute. Oh yeah, the birds now totally avoid the boat top for some reason I don't understand! ROLLOFF it WORKS.
