Paint chip repair on black Boxster: LANGKA or Dr. Colorchip or other?

[healthservices]

I like to try Dr. Colorchip for one of my cars as I have a ton of chips. But right now I just use the factory stuff and it is slow and hard.

I used the Dr. Colorship a few years ago, working on some quite small chips (smaller than match head-sized for the most part). It's really easy and does a reasonably good job. (If you look at all close, you can still see them...but they are definitely better than before, especially since the primer---which is what was showing previously---is stark white.) If you do a Search on "Dr Colorchip" and "Langka" (which I haven't tried), you'll get all kinds of hits.
