Some parts are designed to just let surface rust form and protect the metal underneath. You'll be long gone before it rusted enough to be a problem. Coating parts is an expensive process and it's not practical to do so on parts that are not easily visible. I've purchased more than a few new cars and trucks over the years that I also turned into show vehicles and have always had to paint or remove parts to coat no matter the brand of the vehicle. Surprisingly to a lot of folks , most buyers never crawl under their rides to even notice .
