On an MX5 NB (1998 - 2000), use almost always causes minor damage in paintwork, especially on the nose, wheel rims and other parts that take a lot of punishment from the outside. Such minor damage seems harmless, but as soon as bare metal is exposed, moisture gets free rein. A paint marker helps to seal that spot neatly and keep the color image of the sheet metal clean. Especially when the surrounding body parts are also kept in good condition, the whole looks better.
