Im new whats up people!...but just a FYI I have had many bumps on various cars Subaru,Mazda,Accord and every time I just get my Heatgun out and "pop" out it comes. Chances are that the sunshine is what did your repair for you.

One day my wife comes home and says...honey I hit the pole at the bank I walk outside to see the bumper has almost a perfect round circle in it...so I pull it off and sit on my front step of my house with the heatgun taking out the bend.

I hope this helps you next time you get a dent.
