Is there anything I can do to protect my older truck (ext&undercarriage)fr salt? on 2005 Chevrolet Colorado

I had a detailing shop tell me that there's nothing that can be done at this point. I would simply be covering up the corrosion that's already set in. THere has to be a way to seal it from further corrosion.
