A full polishing range.
From cutting and one-step correction to final finishing.
A lower pane or neighbouring section may receive runoff in addition to direct splash. Record that exposure before comparing visible marks between coated areas.

Identify the pane faces and observe the normal use pattern where practical. Note where water crosses a frame, fitting or adjacent pane. Keep the location record simple enough for the homeowner to use during later reviews.
Compare dry surfaces after an appropriate cleaning routine, not one freshly rinsed area against another with old residue. Record the cleaner and drying method. Exposure differences can remain even when the care method is consistent.
A concentrated mark pattern does not by itself establish missed application or product failure. Review coating history, cleaning and the water path together. Keep unknown causes explicit and seek technical assessment where needed.
Follow the product and glazing guidance while giving recurring runoff locations appropriate inspection attention. Record changes after any relevant enclosure work. Assess later observations against that revised history rather than an unrelated pane.
No. Compare actual exposure and maintenance before attributing the difference to coating performance.
