Hi I just purchased a brand new 2019 WRX Sport Tech. I live in Ontario, Canada and we do get a lot of snow/ice therefore a lot of salt on the roads. The dealership tried to sell me a Final Coat Rust Module for $1000 but i refused. Seemed like a scam to me. Just wondering what are peoples thoughts concerning the best way to rust proof my WRX? Also, is the stock paint/body relatively resistant on its own to chips and rust damage? Thank you!
