Would you consider Space Grey dark enough? I was flipping through my pictures but I cannot find any that really show the line
Mine is cut about 3 inches in front of the "power dome" on the hood. Overall I am happy and the line does not bother me much and is not all that visible either. The hardest part is keeping wax from getting up against it every time I detail my car. Spend a little time getting the excess wax off and you shouldn't have a problem (especially important on a black car).
