A baseball from a little league game hit the side of my car. It left a small dent. It looks like it can pop out.

I tried a plunger with cold water...didn't work.

Will boiling water make a difference? Or just mess up the paint?

Any other ideas? I don't want to spend a fortune on this repair.

Thanks!

 

I don't think hot water will be warm enough, also you won't be able to direct the heat all around the dent as you could with a torch. Can you get access to the dent from the other side? Then you can push the dent out with a suitable hammer/counterhold, or God forbid,-drill a small hole in the center of the dent, screw in a plate screw in the hole, pinch the screw's head in a vise grip and pull the dent out.
Most of the methods that car body shops use usually mess up the paint.

 

These companies do amazing work:

if you can get at the back side of the dent, work your way from the edges of the dent back towards the center with a wood block or similar to try and massage the dent out
