Abstract:
The invention is directed to a method for determining repairability of an original clear coat applied over a darkly pigmented substrate with a corresponding repair clear coat used in repairing damaged original vehicle coatings. The method non-destructively determines the refractive indices of the original clear coat and the corresponding repair clear coats by acquiring the reflection spectrum of these coats with a spectrophotometer with d/8° measurement geometry with and without the specular components followed by determining the refractive indices with the assistance of the differential spectrum between the reflection spectrums with and without the specular components, and then comparing the refractive indices to determine difference between these refractive indices, wherein when the difference between the refractive indices of the original arid repair clear coats is within an acceptable range, the repair clear coat is used for repairing the original clear coat.
