This foam sealant not only keeps pests outside, but it also helps to air-seal the home, saving on heating and cooling costs. Customers have had mixed experiences with this product. Some have found it difficult to control and messy to use, with the foam expanding unpredictably. Trimming the foam can be challenging, and the remnants tend to cling to surfaces due to static. Others have found that the foam does not expand as much as expected, requiring multiple layers to cover holes effectively. There have also been reports of rats and mice being able to chew through the foam, with customers suggesting combining it with steel wool for better effectiveness. Some customers have also complained about the color of the foam, as it may not match the advertised "gray" label and can turn yellow over time. However, there have been positive reviews as well, with customers mentioning that the foam worked well for small patch jobs and was perfect for their specific needs. Overall, the reception of this product seems to be mixed, with some customers having success using it to keep pests out, while others have had issues with its usability and effectiveness.
