Boiling water on bumper

[PlanZero]

So I've seen a few of these you tube clips of people pouring boiling water on dented bumpers and the dent pops right out. Anyone ever try this? Doesn't it damage the paint? I have a small dent on my rear bumper and I was going to try this.

How does the rear bumper dent?

Not sure how this would work on plastic. Works on the body though. You need to dump cold water or blow compressed air on it to get it to shrink back immediately after the hot water.

Wouldn't hurt the paint any more than it is already hurt after being damaged.

heat gun and a wet rag is how I do it.

You want the dent and the entire surrounding area heated up. Best method I've found is put the bumper in the can on a hundred degree day for a few hours, works like a charm. Otherwise, use heat lamps to slowly heat the entire area..

It definitely can work, your heating the surface making it more pliable. Colder is stiff and brittle. Certainly worth a shot if your paint is in decent shape to hold up.

When I did paint and body work a we would heat the surface with a heat gun and push it out by hand. So I guess hot water would have the same properties.Be careful not to get it to hot and bubble the paint.

In some cases you don't even need heat, but if its on any kind of crease you will more than likely need heat. Any type of heat will work and make sure the surface doesn't get too hot just as u lost said, it will bubble the paint. It does take a lot though, don't get it any hotter than being able to keep a finger on it for more than 2 seconds.

A basic heat gun is like $10. I've had luck popping out dents without using any heat at all but it definitely does help.

The hottest you can get water is 212*F..... That's not hot enough to damage anything but your hand.
