hail damage???

i'm not quite sure if this is the best place to post this, but i couldnt find a better place. i have some hail damage that was on my car when i purchased it. all of the dents are small, but there are more than just one or two. how would i go about getting rid of these?? i know i could go the body shop route, but that would be fairly expensive i imagine. any ideas or tips are appreciated. thanks!!!
