Confidence: medium. The customer has performed unauthorized modifications to the glazing beads (removal and shortening), which is outside normal VDC manufacturing scope. The bead snap fit failure is a direct result of customer alteration, not a VDC production or assembly defect. This appears to be a customer request for replacement due to their own modifications rather than a warranty claim for a manufacturing fault. Recommend clarification on whether VDC should replace or advise customer on proper reinstallation of original beads.
