Personally I would forget about it. They rustproof the cars so good nowadays you don't need extra proofing.
I live in the Chicago area and they USE SALT .... a lot of it and I haven't had any rust issues with any of my vehicles in the last 20 years. Just keep your car clean and touch up any nicks and scratches and you should be OK.
