trim finishing hammer

Id like a metal edge to back the part on so I could reform the edge. May get a piece of 1/4 scrap and chuck it in the vise vertically as a very small edge anvil. Its just a strange shape, the leading edge of the 65 Barracuda headlight bezel that always gets dinged up. I got it beat out pretty close. its soaking in EZ-Off now to strip the anodizing off so as to polish out the file marks made knocking down the slight scars. and high spots.
