opinion. I would just mold the side skirts lines and the rear. If you have the stock bumper I wouldn't even attempt the molding of any lines.. just cause the stock bumper is well made with that line. Any other front spoiler should have the Z's lines molded out in my opinion (except for Jspec one- has lines). Love that look. I plan on posting some pics here in the next day of the close to finished product... I'll forward you some as soon as I get them shot.
