I bought this after reading the other reviews as I was looking for a long lasting product. I bought two as I have a very large three car driveway. The packages came very well boxed and sealed in a plastic back to prevent leakage. Funny thing is, they were delivered them to my front porch with the "This Side Up" laying on its side. Hence the reason for the sealed bag. It is heavy to lift and pour into a yard sprayer, but the pop out pour spout helped tremendously. Followed the directions, which are clear and easy to understand and finished in about 45 minutes. It has been about 8 hours since I cleaned up and it is mostly dry. And it is almost impossible to tell I did anything, driveway looks clean and clear. No smells, ne mess and a wonderful product. I've already started spreading the word. Thanks Foundation Armor!
