There is actually a method to filling in chips that doesn't include a respray.
1-Basically after cleaning the chip with thinner and degreaser
2- take a piece of 600 grit sandpaper and using a loose leaf hole punch you cut out a small piece and glue said piece to the top of a pencil eraser.
3-Sand inside the chip to remove the jagged edges by turning the pencil against the surface.
4-I recommend calling Tower Paint giving them your vin# and they will send you a color matched can of your Boxster's paint.
5-dip a tooth pick into the fresh paint and fill the chip.
6-Once it cures follow up with a clear coat and allow to cure as well.
7- Proceed with an 1000 grit sand paper (after taping around the chip) and smooth down the new paint, similar to removing overspray.
8-Follow up with a rubbing compound to remove the marring from the sandpaper,
and finish with a your preferred waxes and polishes. The turtle wax chip stick (at this stage only) isn't too bad actually if it matches your car's color.

I've seen pretty impressive results using this method on the chip ridden mirrors and bumpers of dark colored cars.

p.s. The factory Arctic Silver touch up kit didn't match my my Paint at all.
