Black Metal Bumper Dressing?

[PandaSauce]

Any recommendations for dressing black painted steel bumpers/sliders?

I've been using WD40 on my steel rock sliders and roof rack but am wondering if there is something more professional-grade.

Would Chemical Guys Barebones be a good option?

Ultima trim and tire guard works well
