What Customers Are Saying

The product appears to be versatile and effective for sealing various leaks and cracks, with most customers describing it as easy to use and providing a long-lasting seal, especially on flat, stationary surfaces. However, some customers found it ineffective or messy to apply, and noted the strong odor and the need to carefully follow instructions for best results. Overall, the product seems useful for DIY home repair projects, but customers should assess their specific needs and apply it as directed.

I like the flexibility and how it sealed. The fumes are very strong and so make sure to do it in a well ventilated place.
