Scratches That Disappear When Wet: Set a Realistic Polishing Goal
A scratch can become less visible when a panel is wet and reappear after drying. Use a dry, prepared inspection to decide what a polishing service can reasonably address.

Start with the dry observation
Wash and prepare the inspection area using methods suitable for the finish. Inspect it dry with a repeatable light and viewing angle. Mark the scratch location in the record so that a change in reflections does not make you compare two different defects.
Avoid using water as a correction test
A wet appearance is an observation of the surface in a different condition. It is not evidence that the scratch is shallow enough to remove, nor that a coating will permanently reproduce the wet view. Photograph the dry condition when agreeing the service scope.
Test the proposed process
Use a conservative test area appropriate to the identified paint system. Remove polish residue with the approved inspection method, then compare the same scratch under the original conditions. Assess the surrounding finish as well as the line itself; reducing one scratch while creating haze is not a complete acceptance result.
Define improvement and stopping
Agree whether the objective is overall enhancement, reduced scratch visibility or a more extensive correction. Keep deeper or uncertain marks outside an unsupported removal promise. If the process no longer gives useful improvement within the accepted paint-preservation boundary, stop and discuss the remaining mark.
Frequently asked question
Can a hydrophobic coating guarantee that a wet-hidden scratch stays invisible?
Do not make that promise from a water test. Coating selection and scratch correction are separate decisions, and the accepted finish should be judged after the relevant preparation and inspection.
