I use a hole punch to make little circles of wet&dry usually 180 or 240 grit
then I glue one to the eraser end of a pencil and use that in a spinning motion to sand down the chip so that nothing protrudes above the surrounding paint.

then, using thinned etch primer and toothpicks, I build up two coats of primer followed by several coats of thinned paint, allowing each drop time to dry. I keep going like this until the area of the chip is above the surrounding paint.

Once this has had time to completely dry, I use 600 grit and the pencil tip method to sand it back level, then polish and wax.....

Lewis has a nice airbrush and loves this type of 'work' but he is a long way away...

Took me two months to get the paint of my 1989 CSi to look like this:

Edit: Looking at my 635 makes me think Allan might be right about my CDO (OCD spelt with the letters in alphabetical order....)
