Is Flex Seal still in business?

Hello there, I'm curious about the current status of Flex Seal. Can you confirm if they are still operational and actively selling their products? Are there any recent developments or changes in their business model that consumers should be aware of? I'm specifically interested in knowing if their products continue to perform as advertised and if there have been any customer complaints or concerns. Additionally, are they expanding their product line or entering into any new markets? Thank you for your time and attention to this matter.
