Intercoat

[AAE]

If a metallic panel is scuffed with 400 would the intercoat fill those scratches enough to apply base over without said scratches showing up?

Maybe, is there a good reason to chance it? My minimum for high metallic is 600, and even then that is only if I know I will be applying more than 2 coats. On blends and high coverage fine metallics, I use 800.

Even if it filled them, you would still see the scratches as the scratches are a disruption in the metallic surface which affects how the metallic looks. Inter would be no different than regular clearing over a panel with 400 scratches. Don't know if that made sense or not.
Metallic the surface has to be perfectly even or else the light reflections will highlight the high and lows of the scratch. Solids you could get away with it as the light reflections are all on a uniform color. Metallic is not uniform in color.

I was asking for a friend.

If they are going to do it regardless, I'd tell them to use 2 coats and then wait a good long while before continuing.

So,The "friend" is actually one of "the voices" in my head.
