I had it in 2001, then never again. I don't dip, spray, or anything to prevent it.
I do spray, sometimes, with Messenger. Only because I bought a lot of it years ago. It helps boost or turn on plant immune system. I don't know if they even make it anymore. Back when rust first started, lots of people tried Messenger and said they still got rust.
I don't add very many plants each year now, but I sure did from 2001-2009.
I don't know why I have not had rust, at least once, since 2001.
