Clear Coat Over Bare Metal (can it be done)

I really want to leave my 1970 mustang with that cool hot rod bare metal look. here in FL its just too humid to not protect it with a paint or clear. does anyone know how to clear to bare metal? i know most autoclears arent made for it.

like this?

I saw that stuff. Might do some tests with it but I kinda wanted to use a 2 part auto clear.
