WindShield Trim Dent Removal

I normally just shape my own tools as needed from hammer handles. Wood is recommended only because its soft/forgiving enough to "help" prevent scaring. I have went as far as clamping the trim between hand shaped anvils mounted on 2 pieces of wood replacing my vise jaws and pulling the trim back and forth through and incresing the pressure a little at a time. I've even poured epoxy on an unbent section of the trim to form anvils. Saran wrap as adhesion barrier, Play-Doh for damming and/or molding. Trial and error and effort.
