Review on Davis Instruments FSR Big Bottle by Ashwin Worlds

Unbelievable! My sailboat has been in the water all summer on a mooring balloon. I was so worried about the green slime. After taking it out and washing it off, I looked at the brownish-green stains and thought they would never be white again. I applied FSR and in a few moments it was white again. i am so satisfied It takes no time and works like magic. After washing and waxing it looks almost new.
