Hello there. I have a 2003 Wooldridge with a lot of hours on it. Stays in the water all year round. I have recently applied Sharkhide. I love the stuff. I did 2 coats. It resist all stains from blood from hunting, fishing it really does work. The algae that usually grew on the bottom I would of had to power wash off comes right off with my hand. I like it Love it and fully recommend it for everyone.
