Review on Davis Instruments FSR Big Bottle by Jeff Shapiro

My boat has been on the water for 8 weeks. It's usually stored on a trailer or hoist so I started with a nice clean hull. As can be seen from the photographs, the accumulation in water after 8 weeks was significant. I gave it a quick wash before applying to remove the flaking and I still had significant stains that the washing machine failed to remove. I applied the FSR with a sponge, let it work for 2 minutes and then sprayed it on. The buildup usually resolved itself in one application. A couple of stubborn stains I wanted to go back to and rubbed them again with a sponge and they came off right away. Good product.
