I have been straightening metal for over 60 years and it is quite simple . I use a tapered spring leaf putting pressure on the inside and a flat file on the out side bent to accomadate my hand and the file not only straightens the dent but cold shrinks it at the same time. I have the slide hammers and nail weld gun but I'm concerned I will mess up some thing so I just do it the way I know how. I hope this helps
