Black Jack Roof Sealants Editorial Review
The Leak Stopper Rubber Flexx Sealant is a liquid rubber that comes in an 18 oz can. It is designed to fix leaks and is ideal for use around skylights, in barns, and sheds. While temperature and humidity can affect it somewhat, it appears to work well in most cases. However, one customer felt that it did not spray in a smooth or even coat and was not effective in sealing leaks, even with two coats.
