I had mine media blasted, epoxy primed, and filled the seam with 3M panel adhesive. The 3M panel adhesive is 2 part and is wonderful to work with and is as permanent as it gets. It does not take much to fill the crack of the pinch weld. When you are done, you should not be able to tell where the pinch weld was. It should look just like the top of the belt line. I see too many high dollar rebuilds with seam sealer spooge under the expensive paint like they did it with a finger. Seam sealer doesn't last either.
