Paintless dent repair

[8ml8]

Has anybody tried the paintless dent repair method of freezing the area around the dent to contract the metal and then quickly heating the area up to make the metal expand thereby popping out the dent impression?If you have what did you use to freeze the area and for how long also what did you heat the area with and for how long lastly what were the results.Thank you

i have heard of heating the metal and then applying cold, with say a heavy rag in ice water. now this was on bare metal, where you can easily use a torch to heat the metal. i wonder if a heat gun will work? as far as the process you are suggesting, i am not sure how you would heat it fast enough to make it contract significantly. i am not saying it can't be done, i just don't know how it would be done. freezing it wouldn't be too big a deal. how this all translates with a painted surface, i don't know for sure. i suppose it would have more to do with the type and quality of the paint.

did that even help a little bit?

later,

ryan

I was under the impression from what I've read that freezing contracts and heating expands are you saying use heat to contract?Hopefully somebody out there has tried this and can tell us if it works or not.Thank you

ya, basically you heat the metal, and then "shock" it with cold and it contracts suddenly. very common in body work, at least when you don't have access to a complete auto body shop.

Heat would damage paint. The method is used on bare metal with torches and water or the best a shrinking disk mounted on a hand grinder. The only paintles repair I have heard of was sold on tv (at least a cheap cosumer type) which consists either suction cups and epoxy glued pulls being attached to the dents and pulling them out. I think walmart has a kit for dings. Other methods include pushing rods and rollers used to push and smooth small dents that dont have any sharp angles.

I've used it for years on non-kinked dents, paint intact, by using a heat gun and liquid CO2. Easy as pie...

Swagger that sounds really interesting. Never seen heat used on painted surfaces, except or stripping. How about a thread write up Should work for the <$50 thread. I dont have any nice painted metal myself but I'm sure alot of people would dig this info.

get yourself a can of duster... then use a heat gun to heat the dent up... then FLIP the duster can upside down and spray all over the dent... POPS right out! would blow your mind... the free-on in there is super cold and works great... if not you can also use dry ice...
if all else fails, take it into dent busters or something like that, they have worked some amazing feats on gas tanks for me in the past... exp on the tops of old tanks... some of the newer tanks are duel ply so they do not come out as easy but hey! most will give it a go and they are cheap! paid 20 bucks to get 3 pulled out of my girls tank when my drunk azz friend tossed me a beer box with the bottom opened, cans crashed down on her tank!
