Holograms and buffer trails: how to spot a bad polish job at handover
Holograms — also called buffer trails — are the signature defect of rushed rotary work. They look like faint, wavy ribbons of micro-scratching that shimmer and move as your viewing angle changes, usually in fan-shaped arcs matching the operator's arm strokes. They are caused by an aggressive pad and compound that were never refined with a finishing pass, or by a dirty, overloaded pad dragging spent compound across the paint. On silver they are hard to see; on black they are unmissable in direct sun.
The countermeasure is a proper handover inspection. See the car in direct sunlight, or run a phone torch at a low angle across the bonnet, roof and doors — horizontal panels take the most work and show flaws first. Look for hologram ribbons, compound dust in panel gaps, white staining on textured trim, and any burn marks on edges and creases. A confident technician will hand you the inspection light themselves, and if you booked through tamam, checking before the job closes out beats raising it afterwards — same-vendor rebooking gives a good operator every incentive to hand over clean work.
