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.
Here is the trap: an operator can hide holograms completely under a filler-loaded glaze or wax. The car looks spectacular at handover, then two or three washes later the fillers rinse away and the paint looks worse than before — the original swirls plus the buffer trails. This is the single most common complaint pattern in the polishing trade.
