Sorry, I wasn't very clear.
I use the stuff not as a coating, but just as a way to remove the rust from stainless.
I soak the part for a few hours and then rinse it with water, let it dry and lube if it needs it.
It makes the stainless look pretty much brand new without any scrubbing or buffing.
I was just wondering if anyone else used it. I use it on old clevis pins, screw pin and snap shackles. Just about anything that is stainless. It eats aluminum like candy.
It seems that the acid only reacts on the rust not the metal. But I'm not completely sure that it's a good idea.
I have used it on a steel trailer before painting. It does cause the rust to change color. I guess that is the purpose for which it was designed.
