First, the 2 gallon cans I bought had dents all over them. No leaks. The box they came in was too big and without adequate packaging. It's a miracle they didn't leak. The stain itself covered the previous stain very well (Olympic Waterguard Honey Gold). The Flood patch was much thicker than the Olympias patch. I applied it with a roller and it went on very easily and I used less than I expected.
