I painted my ERA with the body on as per ERA. One reason is because you have to stretch the body (pull it apart at the sides) to get it over the frame. It will not crack the body but may crack the paint. You should have ERA powder coat the frame and bond the body, they will align it all properly. This is the foundation for the entire build process and worth every dollar. I painted all the parts at the same time but off the body (doors,hood, trunk) and had no problem. Good luck
