Thanks George, Going to give it a try and see how it comes out. I have a few body lines that need done. I am using short strand fiberglass then top off with glaze. Is this a good method?

I would use a quality, regular body filler and change your paper often. You want sharp paper. As your paper dulls, you have a natural tendency to press harder. The paper should be doing the work. Pressing hard while blocking makes waves.
Your body filler looks undercut, judging by the obvious edge between the filler and the metal. Your body filler edge should gradually fade away as the repair area becomes level with the metal surrounding it.
