Rust proofing my M3

ExoticM3 · 09-24-2023, 08:40 PM

I daily my M3 year round and I live in the Midwest so the winters definitely take a toll on our vehicles. I want to know what is the best way to go about rust proofing the M3?

Some type of underbody coating is best. Pay the most attention to all the body welds and the rear subframe. another one that corroded on my car were the hydraulic line fittings. they don't fail, but they basically seal themselves.
