I have a few dents in the upper rear cab that will need pulling out, so I bought a small slide hammer and some glue-on tabs used for Paintless Dent Repair. The youtube videos make it seem like it would be fairly easy, but maybe it's the thicker sheet metal used on our trucks. The cab is in primer, but with no access behind the rear panel to bump these out, I thought it might work. I couldn't get the tabs to stick on tight enough to do much, although I did reduce the depth of one by maybe 1/16". I tried sanding the primer to smooth it off, but still couldn't get the tabs to stick tight enough to do much moving of the metal. The glue lets loose either on the primer or the tab.
My next step is some weld-on studs. I have a couple pairs of small vice grips that I'll weld a nut on to attach the slide hammer.
Has anyone had success with PDR?
