How many layers of Marlin are applied to a soft patch?

The correct answer is that two layers of Marlin are applied to a soft patch. This procedure is a standard practice in ensuring that the patch achieves optimal durability and effectiveness. The use of two layers helps create a more robust seal that is essential when repairing or strengthening an area, particularly in demanding conditions. The dual application allows for better adhesion, enhanced protection against environmental factors, and improved resistance to wear and stress over time. This method is particularly crucial in applications where the integrity of the patch is vital for overall system performance.
