Krown Rust proofing, or just wash undercarriage regularly?
I just moved to Ohio this year, and I just got a 2023 mirage. As winter approaches I have considered getting a Krown rust proofing treatment which costs $130. I made an appointment for a few weeks from now.
Alternatively, I could just wash it regularly underneath to get any salt off, I have found a trusted car wash where this would be convenient.
For a 2023 Mitsubishi mirage, is a Krown treatment worth it?
