When I bought my car it had the moldings on them, but I hated them so much I got them removed the very next day! A friend of mine owned a detail shop at the time and with his help we removed them, but it took us about six hours! Getting the glue off the paint was the most time consuming part, as the molding itself only took a couple of minutes to remove but it left behind a thick glue residue. Once we got the paint all cleaned up, you couldn't see any evidence at all that they were there, no lines in the paint, nothing.
