ive had great luck with Duplicolor Engine Enamel matte black. dont worry about the 'engine enamel' part. i used it on my Fit's fog lamp surrounds about 4yrs ago and still today after 3winters there is barely any chips on it. very durable.
so durable, anything matte black i use this stuff.
you can pretty much get it at any autoparts store.
before you start painting make sure you sand down the chip to get it flat...and degrease using rubbing alcohol. temps needs to be at least 70F and low humidity.
