Dent Removal on the Cheap - Macgyver Style

Ever had a big dent from someone leaning on your car or doing something stupid and causing a big dent? I had this problem a few years ago on my old 1994 Toyota Corolla. I didn't have auto insurance, had way to much debt and I was too cheap to get it repaired by a proper workshop. Since I still wanted to woo the ladies,  I "borrowed" the IT guy's compressed air can, got my room mates hair dryer and followed a similar technique to the following you tube clip, to get my car back to its former glory.

Method :

1. Heat up the dented area with the hair dryer for at least a minute on a high setting, Usually your paint can withstand the heat from the hair dryer. This should get the metal soft for the next bit.

2. Now turn the compressed air can upside down and spray the area of the dent from the center outwards in a circular motion. You should hear a pop and hopefully the dent will be restored to its former glory.

This worked for me however I tried it on a friends car who had a dent with a crease in it. This didn't work. Also smaller dents don't work either.

This method works on large shallow dents, anything smaller than a baseball or shallower that 1/4" wont pop so easily. It is the ratio of metal thickness to surface area that is critical and also what's behind the dent as insulation material or stiffeners may also stop this working.  So try this method and if it doesn't work get your insurance to cover it or take it to a cheap PDR place and get them to knock it out.

  3. Bought a used accord a few years back, the second night I owned it, someone jumped onto my hood in the middle of the night, left 4 shallow depressions.

    Talk about depression! Wish I would have known about this trick, I spent the next day with a hammer and towel hammering them out. Still can see them if you're looking.

    Really wish I knew about this!

  26. Tbh, I can't help but be a bit of a skeptic. Does the hair dryer really "soften the metal"? I'd be amazed if it really had any effect. Could be solid otherwise though, and it sounds like it worked well for you. I'm probably just pragmatic.
