I would be more worried about the center section before the axles. Haven’t heard of anyone breaking an axle yet and I know a few cars that are at 700 plus
Good wash, clay bar, da polish, paint sealant, followed by a good wax 24-48 hrs later and you will be good to go. Depending on products used you may need multiple stages of polishing to remove all imperfections prior to the final 2 steps
