I am getting ready to strip weld and paint my 2 containers and have been troubled by getting the walls bent back in to shape so I can weld the scratches shut. There's a couple forklift dent/scratches in the side walls that have deformed the crease patterns and put a horizontal fold/line where the metal rusted through with a couple pinholes. I was planning to get the crease patterns back into shape then clean the rust up to weld over the holes. I am hoping someone has a better recommendation than a sledgehammer an oxy heating tip to beat it into shape.
