Depends on what kind of paint you used. Krylon Fusion dosnt need clear coat.

Suggestion?

Take a can of fast build primer/gray. Then take a some color match paint (of your car) and lay a few cotes. As for the letters maybe silver or red overlays or if your skilled mask it off and paint it.


If you use over lays please clear it a few times, then apply the overlays.
