My beater has 176k and was driven in the Midwest it's entire life. The underside was coated when new and it looks incredible. However, the area under the rocker panels are known to rot if not taken care of. The entire area is a place where water can sit and cause problems.
I got everything prepped, drilled some drain holes and double coated everything with Rust Bullet. I couldn't care less about how the car looks, I just hate Rust.
I'll be doing the front fenders next which are rusty. Be sure to check in the center of the wheel arch, where they all rot
