EDTA-Na2: Bolts from Jimny body

There are two bolts from the body of my Suzuki Jimny Sierra. Both were in the same state of rust.

One of the bolts (on the left) I cleaned only with some petroleum solvent. The other one (on the right) I cleaned with EDTA-Na2 solution.

Looks like there is some bluing (black oxide) on the bolt after EDTA-Na2. I hope this will protect the bolt from rust (red oxide).
