Hail of alot of dents!

[dadio4]

i recently acquired this 99 protege es, and it has about literally 2-3 hundred hail dents on it from a storm in Tennessee this past year. (previous owner) any home garage tips to getting them out? i've heard dry ice placed on the dimple will make it pop back up? (although i don't know where i would get dry ice). i've tried a few times with a plunger on the hood and top and trunk deck. not much happened. it also has a bad dent in the back passenger door,near the door handle, i'll have to take the door panel off to get to. and the rear window pillar on the drivers side has a deep crease in it . would i have to take the head liner down to get to that one?. any ideas of popping these out without a body shop cost would be helpful. thankx

dry ice/heat gun i've heard work. our local hyvee grocery store sells dry ice. also some welding supply companies do too

i have a dent remover meant for cars. It's like a suction cup thing that pulls the dents out. It is very powerful.

i bought a little suction cup dent puller at auto zone, no good though, dents are small. i saw a youtube video where a guy uses a hair dryer to heat up the dent and some cold spray to chill it, and the ding popped out. i wonder what the spray was? is there a "cold spray" on the market?

hmmm. I know that there is a "cold spray" that is used in sports for numbing. That stuff is really cold! Not sure what it is called though.
