Not bad at all. I'd take it to metal, get a couple of packs of J-B Weld, mix a bit at a time, fill carefully using a small plastic spreader and let harden. The regular J-B Weld (not the Kwik Weld) gives you longer working time. Be certain to draw the epoxy up the side of the pinch weld, too. Making this nice and smooth will help a lot when you install your windshield. Then sand smooth. Paint this well when you paint the cab of course.
