If you end up with a chip or a scratch and you want to repair it, you will want to use a fine grit sandpaper and smooth the edges around the chip or scratch down so that there is an easy transition from the good paint into the chip. This is known as feathering the edges. You will want to clean the area using a bit of lacquer thinner to remove sanding dust and any oils and then let this dry. Mask off the area around the chip and then re-apply the base color to the area and let this dry for 20 minutes and then you can go back over it with the accent splatters and it will look great. This type of pattern here can be touched up easily and it will be very difficult to ever perceive a repair was made.
