Shamal season: what dust hides on a repainted panel
The shamal, the north-westerly wind that drives dust across the Gulf mainly between February and early summer, matters to a car buyer in two ways. First, years of suspended dust act as fine abrasive: original UAE-kept cars show a characteristic uniform micro-scratching on horizontal panels and a lightly sandblasted lower windscreen edge. A five-year-old car with a bonnet and front bumper in suspiciously perfect gloss next to pitted glass and dulled headlight housings is telling you those panels were painted recently, whatever the seller says about garage storage.
Second, never inspect a dusty car. A coat of shamal dust is the cheapest paint-defect concealer in the region: it flattens the reflections that reveal orange peel, overspray, ripples in filler and colour mismatch between panels. Insist the car is washed before the appointment, and try to view it in low-angle light, early morning or late afternoon, when panel waviness jumps out. Inspectors carry a paint-depth gauge precisely because eyes are not enough: factory paint on most mainstream cars measures roughly 100-180 microns, while readings of 300 microns and above usually mean filler and respray underneath.
