Question:
Is this sealant a permanent solution?

This dual capability is essential for comprehensive marine repairs where different environments are encountered. -
Question:
What is the viscosity of the sealant?
Answer: The adhesive has a medium viscosity, allowing for easy application while still offering a robust bond.
