I have found that paint chipping is a forever problem. Having a good enamel paint … I use ALK-200 …. that can be touched up easily is a good approach. Using a small brush, a sharp razor blade and some high grit sand paper makes short work of a chip. If it’s a deep chip, a good enamel will let you add layers and fill the chip depression. Make sure you read the paints tech sheet.
