There is a great article in Volume 2, How to Restore your Model A:
I've done headlights, cowl strip, and radiator shell and found wooden dowels work well. Buy a couple feet of 3/8 inch dowel and cut into about 6 inch pieces. Round over the end and tap out dents from the inside. I used a piece of heavy rubber to rest headlight against as I hammered. A piece of 1/4 inch or so rubber works well- like a piece of a truck's mud flap.
Once hammered out, use a points file and lightly file areas punched out too far (careful- it's thin metal). Then sand with progressively finer sandpaper. Down to at least 600 grit but probably finer. After that, the stainless steel ones can be buffed out with 2 grades of compound an buffing wheels.
Good luck- they'll look great.
