The show Outrageous Acts of Science showed a guy removing a dent
from the left rear corner of his car. He poured hot water on the corner
then used a toilet bowl plunger to pull the dent out.
He also had a dent on the plastic bumper. He poured hot water on it
then pushed the dent our with his hands.
Their explanation was that the hot water made the areas surrounding
the dents want to expand. That lessened the force needed to remove

Is there a question here?
But I can testify that yes, a toilet plunger can remove a dent on
some places on a car. My dad did on my brother's car door many,
many years ago. There was crease in the door not from hitting a
pole or anything like that. The door panel was just depressed
and the depression simply popped out using the plunger to 'grab'
that area. Paint wasn't even damaged.

Sorry, I haven't been ignoring you, just now getting back to this group.
When MSN pulled the plug on webtv in 2012 everyone got an e-mail notice
that they could keep their webtv e-mail address if they signed into their account at least once every 270 days.
I've had a laptop since 2004 and that's when I started posting on Usenet
groups with this name. I decided to keep it and another one but use
this one for posting only. One or two old webtv buddies will still
contact me through this name. Most of them I gave my MSN address to.
Different iossue with plastic bumper and steel door. Heat softens
the plastic, allowing it to flex more easily and reducing the
likelihood of cracking.
Popping dammage out of steel door is possible if there is no "crease"
or stretching of the steel. The plunger often works even without the
heat. Hot water to warm up the steel completely, then application of
dry ice will often cause a dent to pop right out without a plunger
(particularly on smaller dents) because the dry ice shrinks the outer
skin of the steel faster than the back part, and the dent shrinks
I have a plunger type dent remover, a big suction cup. Easier to get
seal when wet. It will pull out a dent but not a crease if bent. I
have another tool for pulling creases that is screwed through metal and
banged out with a weight on the screw. Body filler is needed afterwards.
Plastic would be another story and depend on plastic. Plastic usually
breaks and fiber glass like on a Corvette just shatters.
