So i park in the garage, get out and find this chunk of paint missing from my rear right quarter panel, smack dead center.

The damaged area is about the size of a small fly.
Anyone know the best way to address this? I took it to a body shop.. and the guy says my best bet is to get some acura touch up paint, apply it.. and wait a few days, use some 1500 grit sand paper on the area.. and buff it out. He says it will look alot better.
Is this correct?
thanks
Sean
Btw- the car has freakin 980 miles on it
