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.
