Removing rust from the body structure crevices where the body to stub mounts are. This area is semi-exposed and this became filled with road debris. Since the car lived its life in SASK and Alberta, I assume it was exposed to a few rounds of salt. Not much exposure, so no severe damage, but even just once is too much, in my opinion.
I'm trying to remove all of the rust and paint it. Been soaking in Evapo-Rust, Naval Jelly (Phosphoric acid), even HCL here and there but this crust is super tough. Acid doesn't seem to touch it. Evapo-rust is taking a lot longer than usual, and I've gone through a lot more solution that I normally would.
I'm guessing that the salt has mixed with the iron oxide to form some other type of oxide/salt coating
Attached photo is not the greatest but you can see the orange rust/salt crust.... Naval jelly didn't do anything to it. Usually it turns black as it converts rust.
I found another product called "Salts Gone" but not sure what that chemical is.
So wondering if anyone has run into this before...?
