Actually I just found a can I sued to coat my frame its called RP-342, I could have sworn GM had a product of the same but I may be mistaken.
That appears the same or similar to the GM “wax” coating. I bet it’s good stuff. Cosmoline has been around forever. They also make the rattle can version in black color like fluid film.
And knowing what I know now compared to when I left the rust belt 30 years ago I’d definitely have an arsenal of all that stuff if I was battling the chlorides every winter!
