How to Repair Severe Body Rust?

Use a grinder to sand the rusted area, spray some expanding foam, trim off excess foam, wipe clean, and apply a layer of rust inhibitor. Cut a piece of fiberglass mesh, mix resin adhesive with hardener, and apply with a brush. After the adhesive dries, use a grinder to smooth the edges. After sanding, apply body filler, sand with sandpaper, and proceed with painting.
