    After removing the thick undercoat with a heat gun and putty knife. There leaves a thin film of the undercoat. What is the safe and easiest way to remove this film, in prep for sanding?

      If you are removing it to prep for sanding, why not use a wire wheel on a drill ? This will help remove the thicker spots, and get in the nooks & crannys.

      if you don’t want to remove the paint/primer or whatever is on the metal take a big soft brush soak it in gasoline and apply it on the areas. Wipe it down, repeat if necessary.

      Last step take a wax remover and wipe it clean. That’s how i did.

      I didn't like the idea of using heat, and avoided it. Instead I used an air tool, a tool called a needle scaler - best tool I got and it knocks the undercoating off in chuck's, cleans it off down to the metal, and doesn't leave any residue that needs to be cleaned up after the fact . . .

      Too bad that I waited until the job was half done or it would have been done much faster. . .

      Oh well, live and learn . . .

        Spray it down with Gunk Engine Brite Engine Degreaser. Let it soak overnight.
        put Nitrile gloves on and scrub the residue with scotch Brite. Rinse with garden
        hose. Done.
