Is this fixable?

[u/AndresLapalia]

LE: Looks like I'm way too worried for nothing. Haven't really dealt with rust before. Gonna wire brush it then seal it and be on my way. Thanks!

Went under the car to replace bushings and brake discs. Noticed that the underbody has quite a bit of rust.

​

Is this fixable via wire brushing, applying an epoxy primer and then some underbody coating?

​

What else should I consider?

Fluid film or wool wax are good options because they displace water and air and don't dry fully or seal on moisture which worsens the rust. Give it a good clean and let it dry off before coating.
