Outdoor Coating Trials After a Weather Change: Annotate the Timeline
An outdoor trial should preserve its exposure history. A result photographed after unusual weather needs that context before it is compared with an earlier inspection.

Record events as they occur
Keep dates for rain, dust events, storage changes and any cleaning or contamination removal. Use reliable available weather information when needed, but distinguish it from conditions actually observed at the samples. Do not invent precise panel exposure from a regional forecast.
Keep inspections comparable
Check clean surfaces through a consistent supported method and identify any necessary deviation. A dusty dry sample and a freshly rinsed sample may show different water behaviour without indicating a permanent coating change.
Review the whole sequence
Compare repeated observations across the timeline rather than selecting one dramatic day. If samples were moved or treated differently, keep those groups separate. Report the observed change and the uncertainty instead of attributing every weather-related appearance directly to a formula.
Frequently asked question
Should every loss of beading after a dust storm be counted as coating failure?
No. Assess contamination and the documented maintenance process before making that interpretation.
