New streaks need a controlled comparison before changing the whole care system. Review recent changes in cleaner, cloth, dilution and working method.
Inspect a clean, dry panel under consistent lighting. Keep the original application record and identify which area first showed the problem.
Adding stronger cleaners or several new toppers obscures the cause. A streak that changes with viewing angle may need observation rather than more chemical treatment.
The useful outcome is a reproducible condition and a justified next step. Refer persistent unidentified changes with evidence, keeping underlying finish repair separate from coating renewal.
