To fix a single dent (like the one pictured), it is probably not worth the time and paperwork it takes to fill out the insurance claim. Besides doing it your is easy enough --the tools won't cost much, and the instructions won't make your head spin.
You can bang out that dent, fill those nicks, and refinish that paint job with a body hammer and dolly, a sander with a 36-grit disc to remove paint, a putty knife and body filler squeegees to apply filler, a bodyworking file ("cheese grater") to level the filler, a stroke sander to smooth it, an air compressor and spray gun to apply primer/surfacer/paint, and a buffer to shine it all up. Thanks to today's body repair materials-better paints, improved fillers and two-part primer/surfacers-bodywork and painting to a mirrorlike finish has never been easier to do in your own shop.
