Hey Guys,Im looking to ditch the red pinstrip that seperates the brown and gray on my el camino.I was hoping to get some advice on what color to replace the the red with could anybody maybe chop some darker gray or silver on there for me or a color that you your self would think will look good on there to seperate the colors for me.Thanksin advance guys.Hope this photo works
