Shamal season: what dust hides on a repainted panel
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.
Dust season also loads the car's filtration. Ask the inspector to pull the engine air filter and the cabin filter: a filter caked solid suggests skipped servicing, and fine dust ingestion past a cheap or badly seated filter is a known killer of mass-airflow sensors and turbochargers in the Gulf. It is a two-minute check that says a lot about how the car was maintained through the dusty months.
