Question: I have a Fiat Panda, Fiat says that the vehicle does not need additional rust protection or a cavity seal or other corrosion protection, as these vehicles no longer have a problem with it. However, my old car body workshop thinks this is urgently necessary for new cars, since they have found enough defects in older Fiat models, because I do not want to invest money for nothing, I ask for good advice. Thank you very much.
