Contact Angle on a Curved Car Panel: Understand the Measurement Limits
Contact-angle measurement on a curved car panel requires more care than estimating an angle from a bead photograph.
Ceramic Coating Test Panels Stored Face Down: Protect the Reference Surface
A test panel stored face down can acquire contamination or contact marks before the next coating observation.
Why a Fresh Topper Can Confuse a Long-Term Coating Trial
A fresh topper can change the water behaviour of a surface during a long-term coating trial.
Coating Samples with Different Cure Ages: Delay the Comparison or Label the Difference
Coating samples with different cure ages may not be ready for the same comparison.
A Ceramic Coating Test with One Excellent Panel and One Poor Panel
One excellent coating test panel and one poor panel signal a need to investigate variation before calculating a simple average.
Coating Durability Reports: Describe the Endpoint before Comparing Months
Durability reports are difficult to compare when they count months to different endpoints.
A Coating Trial That Changes Cleaner Halfway Through
Changing cleaner halfway through a coating trial changes the maintenance history.
How to Write a Useful Negative Result from a Ceramic Coating Test
A negative coating-test result is useful when it describes a reproducible observation and the conditions that produced it.
Coating Claims with Percentages: Ask for the Denominator
A percentage in a coating claim needs a defined denominator and measurement.
Fleet Coating Trials: Choose the Car, Panel or Wash as the Experimental Unit
Choose the experimental unit before a fleet coating trial so repeated readings do not create an inflated impression of evidence.
A Two-Day Coating Comparison That Separates Product and Workshop Effects
Use a blocked two-day workshop trial to compare coatings without confusing product performance with daily changes in conditions.
When Two Coating Trials Disagree: Build an Evidence Reconciliation Table
Resolve conflicting coating tests by comparing substrates, application, exposure and endpoints before deciding which result applies.
