Dent removal

"whats the best way? ive got a few here and there that annoy me beyond belief saw on youtube that heating with a hairdryer for a minute or two then applying liquid CO2 for a few seconds then waiting will pop the dent right out.. does this work? or any other inexspencive methods are appreciated "

"what ive used before are a dent puller works on some dents not on all though its like a big rubber plunger you can pull your bodywork out with like the one i have is only small and cheap but you can get really big ones with vacume type suction pads and alsorts. the heating and cooling ive never tryed yet but i have seen alot on you tube about this and its been talked about alot so there has to be some form of truth there as the logic and theory is there its just wether it works in real life haha other than that maybe some small companys like chips away dent master etc "
