I tossed it in the trash. Pissed me off. My car is 12 years old and now they want to do something for rust? No thanks. If it's already rusting the only way to stop it to kill, or remove, the rust.
Mine's not rusted. It has "lived" in central VA all it's life and never goes out when the roads are bad/salted (yeah, it happens maybe once a year, in a bad year two or three times). It stays in the garage when not being driven.
Anyone who lives and has to drive where they salt the roads knows how bad if makes vehicles rust. So do the dealers and the car companies. Waiting a decade to off to treat cars for rust is a decade too late to stop it before it starts.
Reminded me of the dealer making excuses for not taking care of the start up rattle issues on my 3.8 while trying to talk me into transmission/cooling system flushing/refilling that costs hundreds of dollars at 1/3 the miles recommended in the owners manual.
Drove my Coupe yesterday. Still fun, after all these years.
