I would apply a few more layers to make sure the chip is level with the surrounding area. I can see my chip more when it is cloudy, when it is bright and sunny the metallic flakes blend in perfect.
Also, the paint from Dr.Colorchip has a clear coat solution blended into the paint. More so than what factory touch paint has. I would polish and wax the area.
