Hello everyone,

so I used to have an old integra that was white, and it had surface rust. My old friend washed it in acid to remove all the rust coloring and it looked fantastic.

I don't talk to him and don't know what type of acid he used.. Does anyone know what I could use?? Please Help!

 

Might have been phosphoric acid.
