If you want the job done right, then yes: grinding, filling, sanding, priming, and spraying are your best option. There are alternatives out there. Duplicolor makes color matched kits which allows you to paint in the smaller chips (it has an abrasive, color paint brush, then a clear coat to go over the top).
