Clear Over Bare Aluminum?

[Color_Dynamics_]

Forgive my ignorance. I searched old threads and came up empty handed. I spent a considerable amount of time cleaning up a 4L60E that has been in my barn the last 14 years. The years haven't been kind. Took a lot to clean up all the corrosion.
My question is can I use clear over bare aluminum/steel? Might be a silly question but I have zero experience with 2 stage and clears. I have intentionally steered away, but I would like some protection while keeping the look of clean bare metal.

Adhesion promoter will help you out over bare metal. I usually clear my panels after adhesion promoter than knock clear down with 400 grit so you have a decent substrate to work on. This way whatever you’re working on is even as well . Here are a few ground Aluminum panels for an idea . They look like a hologram in the sun under the candy colors
Hope this helps !
