WindShield Trim Dent Removal

The trim is off the car. So, I should use wood the support the trim and use a wooden mallet to gently work the dents out? I saw a trim anvil at a web site would it help? http://www.tptools.com/p/2809,170_Trim-Anvil-and-Chaser-Hammers.html. Or is it better to use wooden tools like the mallet labeled "A" at this web site, http://www.tptools.com/p/489,170_Deep-Reach-Wooden-Mallets.html? I figured the wooden mallet came sanded down to fit within the confines of the trim. I appreciate the help.
