We had been looking for a roofing coating for some time. We ordered a gallon in the summer to test it out on our roof, part epdm and part metal. After our initial testing we were quite amazed with the performance of the product. This is the only product that had stopped our leak, and in fact the first time in 4 years the roof did not leak. We since then completed our entire roof and saved several thousand dollars by hiring some general laborers to apply the material along with some people who work in our warehouse. This is the first time that I took the time to write a compliment but you guys asked if the product did what it said it would to let us know so I am glad to do so. Great product and great customer service!
