Yeah I saw a needle scaler I don't need the most expensive stuff just tools that work. I thought harbor freight had it. I also gotta get the punch/flange tool and a small mig. I have 220 ran and was looking at 120volt titanium mig with or without gas. Won't be doing very many panels. All the documentation helps out I did this a long time ago same tools except the mig. We used a body panel spot welder with flange and alot of mud. Thinking no flange and seam is going to look alot better and less mud
