Any advices or tips on how properly doing this? I have no welding experience! Costly to send to a shop? My front right floor pan is badly rusted. I also found my brodcast sheet, was under the carpet but sheet in very bad condition.
Clean metal, the right size wire and settings, and above all else, practice, practice, practice (did I say practice) on some scrap sheet metal the same thickness as the replacement pans.
Then either order you a patch panel or make one. Or replace the whole floor if you want a factory like install
