Car is beginning to show some light rust on the undercarriage. No holes or rot, just rust but it is starting to become 'textured' so it is likely beginning to progress.

My thoughts are to remove it all off with a wire brush. Then use some product like Kleen Strip to remove the remaining rust. This would be a remover, not a converter.

After that I figured some POR-15 or equivalent product finished off by a coating of Wurth undercoating.

Good? Or should I do something different to arrest and prevent future rusting on the undercarriage? Any harm in combining the above products, etc.?

Thanks in advance.
