You can always add more but cant go back.
Etching the metal should be okay if rinsed off well, I hope? I also soak in a baking soda bath afterwards. I'm not ready to finish, so that's why I'm curious.

Yeah, and obviously I misunderstood your formula. For some reason I "remembered" phosphoric acid. I'll try the must for rust. Sounds real good. I needed the phosphoric anyway.
