Just talked with Dan at the Texas office. Very nice guy. If anyone doubts the strength of Pond Coat and it's ability to self-heal, talk with him. He told me that he has shot a bullet through Pond Coat and come back the next day and it was waterproof again. Also, that he has contractors using it in showers where they temporarily nail stuff up and when they remove it, it self-heals and doesn't leak like another product they used. He's checking inventory and going to call me back in the morning to let me know if he has the 15 gallons I need in stock.
