Silent Running SR1000 is a nontoxic water-based vibration-absorbing material that you brush, spray or roll on like paint. It works by converting noise and vibration into low-grade heat, which is then dissipated throughout the surface on which it’s been applied. You can use this Coast Guard-approved product to help cut down on noise by applying it to the undersides of cockpit hatches, the undersides of engine covers, the exteriors of bow-thruster tubes and other interior surfaces. Silent Running is water-based, VOC compliant and dries to the touch within an hour, at which point you can add more coats to increase effectiveness.
