Hi. Trying to repair the rusted out (already repaired badly) panel under the tank. Both edges need fixing. Any tips on make the panel, it seems to be a bloody weird shape looking at photo's online. The plan is to have a vertical flap/lip along the bottom, horizontal triangularish section in red then another fertical section to get up to the weird contoured floor Then make a bendy panel in green to join it all up with existing Cheers
