Hi all, This is one of the jobs I've got this summer, so I'm open to suggestions on best cure/solution. My current thinking is plastic/masking tape around affected area, gently sand to cleanup and remove debris, use that rust-converter stuff (HAMMERITE KURUST 90ML - Rust Treatment /Killer) to convert/revert it to something solid, give it an undercoat/protector (CarPlan Tetroseal Underbody Underseal Sealant?) and then paint over the top (rattle cans?) Anyone any comments on the above plan, or can tell me I'm talking rubbish and tell me the best solution!
