fish oil rust prevention

I've had good luck with this and knew it had fish oil in it., but did not realize untill now that it needs rusty metal to work right.
I read the FAQ on that before posting this.

Although when I've wanted to use automotive paint over it, I always top coat the Rustoleum with rattle can laquer primer.

On airplanes we used something called Dinitrol
I understand that LPS3 is the same thing.
Don't breath it. It will coat your lungs.

One of my Darts had Zeibart when it was new.
It has the yellow plugs in the panels.
Probably something like that.
