Questions for Evaporust Users

Thank you. It's a little worse than the photos show. There are a few pin holes on the outer rear edge that I'll need to cut out and repair. I'd rather treat the rust as best I can than just cover it with goopy paint that I'd likely get more on me than the rust metal. Just trying to decide whether to take the acid approach, or give evaporust a try.
Evaporust is non-toxic, and safe for You, pets, etc. It also works extremely well, & helps protect the metal after it has removed the rust. I have done a set of GLH coils, tools(some alloys will have a black iron film when done, scrub scrub scrub), and other suspension & sheet metal parts. I oil the tools, & oil/paint/etc. whatever is needed for the parts. I've painted right over treated strut mount plates & spring seats just patting them dry, with Rustoleum, still look great 10yrs. later. I've used bottles, jugs, & other containers simply filled with water to displace large volumes of airspace to reduce how much product is required to cover the item/areas.
