just tried the hairdryer w/compressed can of air technique = no dice. I did it twice with no results. At least there's no damage though. My dents are small so maybe that's why it didn't work
 
I think I'm going to try the dry ice thing....if I can find dry ice here in Hawaii. Lol
 
I'm thinking that it might work better in Hawaii. It's pretty cold here so when I "heat" it with a hairdryer it may not be hot enough. I'm going to try again when it's a warmer day and then probably again in spring and summer. I have dents that I need out.
 
i think i am going to try the canned air tomorrow. i have a really annoying dimple dead center in my rear bumper. its shallow and wide, the perfect kind of dent for this technique.

they said that this wont work on "door dings" or deep and small dents. pretty much only the kind that look like you could push them out with your finger if you had access to the other side...

So a dent that looks like a headbutt your door? (bang)

I think that the technique only works for metal panels. Plastic tends to undergo plastic (the word plastic has nothing to do with the material, it's just what it's called in mechanical engineering regardless of the material) deformation while metal requires more stress to do so. Therefore, even when dented, the metal wants to go back to its original form. On the other hand, when plastic is dented, it relaxes and keeps its new dented shape.

if that is true then explain to me how heat applied to bumper makes it pop back out on its own??? IE removing a bumper with a dent in it and let it set infront of a heater for awhile. Yes I have done this before. The plastic wants to go back to its orig shape Its not 100% but close enough.


Edit: I agree with you that the above methods only really work on thin metal which is why some cars it works on and others not to much.
 
It really depends on the size of the dent and where.

Really big (some dumazz sat on my hood or roof) are good candidates for a toilet plunger with grease around the edges and a good pull.

If the dent is straight in (no metal wrinkled and not on an edge or seam) try to remove the door panel or inner fender and push straight out in the opposite direction and spot of whatever caused it. Hammer carefully - don't over-pop it!

The heat gun works well for softening the plastic bumper and letting you re-shape it. Work it around/moving so you don;t over-heat and blister the paint. Take your time.

And some you can't do anything about. BUt for alot you can at least try first!

A lot of times people wil meet up and do a bunch of cars with dry ice on a good hot summer day.
