I've been using the pointy end of a wooden toothpick to apply paint from my dealer touchup pen. I just have to touch the tip in the middle of the chip and let capillary action do the rest. If the chip is bigger than a pinhead then you may get a raised area if you use too much paint. Use very thin layers and build up the paint slowly over a few days and you might get away with not having to wetsand.
Obviously, if you have many chips to do it will take you a while.
