detailer

One who gives details of something.

[…] the general disposition of those memoir writers and detailers of state secrets (even when there is no malice) to sacrifice truth for the sake of a more striking effect.

One who details (cleans cars).

In the case of Richmond Hill, the torch has been passed to Simcha Waisman, 62, vice president of the neighborhood’s block association. Mr. Waisman’s devotion to neighborhood welfare is legendary; he has been known to stake out freshly painted walls for as long as a week, waiting to catch someone painting graffiti. Mr. Waisman drives a cranberry-colored Expedition, which he says has been so marred by dripping creosote that his detailer now refuses him service.
