    },
    {
      "question": "Can GSM predict non-stick performance?",
      "answer": "No. Release depends heavily on the coating system, coat side, application, curing, use conditions, and test method."
    },
    {
      "question": "How many GSM options should a buyer trial?",
      "answer": "Trial the smallest technically justified set that brackets the target; too many uncontrolled variants add cost without producing a clear decision."

    {
      "question": "Should price be compared per kilogram?",
