The roof had some body filler in places, figure #185. "Old Guy Scott" uses a vixion file to show the high and low spots as he shapes the metal back in place figure #186 and #187. The rear section, figure #189, had to have heat shrinking work, you don't want to load up on plastic body filler. In figure #190, you can see the metal is perfect. In figure #191, polyester primer is ready for final block sanding. If your roof has surface rust or not, be sure to metal prep it several times Figure #190, otherwise you could mess up a good paint job in the future.
