The Black Jack Driveway sealer manufactured by Garner-Gibson Company is a worthless product and the company is ever more worthless. They have a 5 year warranty for their product but when you submit a claim they do not honor it. The product didn't last one winter. When I submitted the claim they said it was too cold when I applied it, when I followed thier directions word or word. Thier directions say to apply the product when it is above 65 degrees. They denied my claim by saying it got below 65 overnight. What a piece of *** company.
