The same model in two colours can need completely different products. Reaching for an aggressive compound on a car that only needed a light polish removes clear coat for no reason; reaching for a light polish on hard clear coat wastes a day and fixes nothing.
An unusual combination, and the one that catches owners out. A BMW can shrug off a polisher and still take a permanent etch from a bird dropping left on a hot bonnet for an afternoon. Hard does not mean tough.
Given how readily this paint marrs, anything acidic sitting on a hot panel is the real enemy. A coated surface gives you a buffer and a much better chance of removing it cleanly before it etches.
Owners report BMW paint as sensitive to chipping despite the hardness. The nose, mirror caps and the leading edge of the roof take the worst of it on any car driven at highway speed.
