some touching up tips wanted 

I just notice there is a rock chip on my passenger side front fender.. And I plan to touch it up before repainting it. As a plastic modeler before.. I was thinking about something. the ground paint, should I paint a white ground before I apply touch up ? or I can just forget about it and apply the touch up directly on the bare metal?

Ppl telling me just to leave the chip as is.. but I rather see something red than bare metal..

any help is appreciated..
