A sharpie and a tall glass of the first one hurts the most.
Seriously though sand it down and use wood shaving dust and wood glue to build up the body edge. You may have to play with stains as the glue could cause a color shift.
For those not staining, sand and wood filler followed by primer, paint 3 coats of color, wet sand the color to a mirror shine (google is your friend for this step) and then 4 coats of clear followed by more wet sanding. You may also want to look into a technique called feathering where you sand less coats as you go outward to allow better blending of the paint and clearcoat.
