I've had about 3 or 4, mostly to the front including the edge of the bonnet and also one on the rear wheel arch.
I ordered some paint from fixachip, as at the time I couldn't get one in my colour from fiat. This paint came in a small bottle with a little more than you normally get with a touch up stick.
The best technique I have found is NOT to use the supplied brush on the paint stick, which is way too big for the job, but to use a very small good quality artists brush.
I apply a small droplet into the chip hole so it touches the sides but doesn't go over, and apply just enough so there is a slight raised droplet compared to the surrounding paint. I then leave it a day - the paint will dry to below the level of the surrounding paint. I then do the same again, apply another very small amount to raise it above the surface again. This ensures the paint is almost level with the edges of the chip when it dries and gives the best result, and no brush marks. At no point should you brush the paint on !!
I again leave it to dry for a day, then use auto glym super resin sparingly to polish any remaining raised paint level with the surrounding finish.
If you feel unsatisfied with the job at any stage (even after you've just applied the paint or maybe put on too much) , you can use more polish to soften and remove the paint and start again. I then apply a small amount of laquer if I'm satisfied with the final result, and polish it a few days later.
I've found this gives a reasonably good result for not a huge amount of effort (and I'm picky !) so you can barely see the chip unless you know exactly where it is and stare hard at it !
