Yesterday's hailstorm was very rough and my car although parked inside garage but unfortunately the trunk was not in shade. There are around 15-20 small dents on the trunk and as the color of my car is black plus i try to keep it very clean all the time those dents are really haunting me now 
I tried searching on forums for any solution like vacuum suction or dry denting but couldn't find any answer. So can any body guide me what should I do to remove those dents? I took it to a reliable denter but he was of idea that these cant be repaired and either i let them like this or i should replace the trunk with a new one same color (which i dont want to do).
Also read somewhere to use hair dryer to heat up the dented area and then try removing it. Does that work?
