From playing with cars the only way to make to rust go away is to chop it out. But have used like jenolite which has been good. But you need to stop the chemical reaction that converts iron to iron oxide and that would be to take away the oxygen, so a decent hi zinc content paint. The one that I use is galvanizing spray as it contains a very high zinc content.
But we can talk about this sort of thing if you want.
