Shrinking Disc Help, Please
I'm doing quarter panel replacements on my '47 Ford and finally got a chance to use my shrinking disc, but I'm not sure I'm doing it right. After welding in the new panel, there is an outward "bump" along the top horizontal seam where the two panels were butted tight. I ran the disc along the seam several times but I'm not seeing any change. Am I asking too much? I've hit the seam and the areas about 2" - 3" on either side of it until the seam (high spot) turns blue...
