How would you mask this?

How would you go about out masking the two circled sections for the cleanest possible lines? They will be black and the rest of the hood red.

I’m thinking airbrush the two pieces black, then mask them with liquid mask, then airbrush the rest of the hood red. Ive only used liquid mask once before and it slightly discolored the paint underneath so I’m nervous about it. Though I left the liquid mask on for about a week so maybe I need to remove it sooner.

Thoughts?
