I recently bought a used class C Gulfstream and there's some rust underneath. It has been in Florida for a few years and hasn't been driven much over the past year. Can anyone advise me on the rust issue? Is there something I should do now before it gets worse or is that to be expected? Also, is there anything I can do to help prevent more rust? I have a cover on it but don't have a garage for it. Thanks, if anybody has any ideas.
