What should you not use Flex Seal on?
Could you please elaborate on the scenarios where Flex Seal should not be applied? Are there any specific materials or surfaces that Flex Seal is not compatible with? I'm particularly interested in knowing if it's suitable for use on delicate fabrics or electronics, and if there are any potential risks associated with using it in those situations. Additionally, are there any environmental concerns or safety hazards to be aware of when handling Flex Seal?
