U seen those car dent removers... normally the dent goes into the body.. and in ur case it the opposite.. it looks like a bulge. why don't u buy those dent repair kit. open ur bonnet and use the product as instructed. i had a bent in my bonnet.. what i did was open the bonnet and hit with hand hand on the bend area and it worked.. so...I am not sure.. but u can keep a towel on the bulge and hit it with ur hand..
