I’m using MIG. I appreciate all the responses. I think you guys have given me some things to work on. 1) I will tighten up the gap between panels 2) Try use some kind of backer. 3) I’m already going so slow but I think I need to assess panel warpage with a straight edge much more frequently 4). Remove excess material more frequently, not waiting until the end to do all the grinding. I need to work on planishing technique I think, it’s kind of the worse part of the job. Ill give it another shot this week and see how it goes. Thank you
