There are some aspects to consider. While the application is straightforward, it does require waiting for 5 minutes before removing excess, which might be a bit inconvenient for those looking for an instant solution. Additionally, while the formula boasts heavy-duty protection, the long-term effectiveness may vary based on the specific conditions of your surfaces and frequency of use. It's also worth noting that the sealer comes in a single 32-ounce bottle, so for larger jobs, multiple bottles may be necessary.
