A easy and paint safe way for gravel shield spats is PLASTIDIP.

Tape off the area with 3M Painter's Tape.
Spray 10-15 light coats of flat black (or other color).
Wait about 5 minutes or until product has set but not totally dry.
Remove edge tape at slow sharp angle for nice clean lines.

Don't be afraid of mistakes. Just curse a little, peel off (in one piece) and redo.

Holds ups well for at least a couple years then just redo.
Will not affect paint or leave residue.
Spray application is more effective at handling compound angles on Cobra hips.
Apply their "glossifier" product if you prefer a shine
