I was able to clean up the front grilles. They were covered in oil/dirt and such. So after about an hour or so the three grilles are now clean enough to store.
I am still working on cleaning up the headlight door mounting brackets - driver and passenger side. They still need to soak in the evapo-rust. I did find a headlight adjuster ring that needed cleaning and corrosion control. That part is also soaking in the evapo-rust container.
Hopefully tomorrow I will be able to paint these remaining parts.
I found a couple more headlight adjuster rings. I sprayed them with paint stripper and removed most of the paint. I added those to the evapo-rust container to soak.
