Getting ready to place another order with LMC for working on my 3100 Cowls. They sell a complete repair cowl or just the lower section. All that's rusted out is the lower section, but it appears by looking at others folks handywork, they are replacing the entire thing. I'm using a flanging tool to marry the panels together, so I'm wondering how it will look at the edges with a flanged connection. Any expert advice here?
