How are hatch and portlight leaks resolved?
Where a leak appears and where it enters are almost never the same place: water enters at the frame, travels inside the laminate and emerges as a stain metres away. Sealing under the stain therefore fixes nothing.
Why it works this way
Moisture readings establish the boundary of the wet area, and the source is traced back from there. It is slower than resealing and it is the only method that works once.
