Comments about Sealant Foam Spray, 12 OZ:
I used this to fill a gap in hull's foam which was compromising its strength and resulted in a stress crack to the fiberglass. All I had to do was drill a hole from the inside and use the spray tube provided to inject the foam into the hull. The foam expanded perfectly without any bulging to the surrounding hull and cured strong giving the hull area its durabilty back! It is also easy to sand for a clean finish once dry.
