Yup, the swoop (i.e. U-Stripe) on my 06 R53 got so bad I finally pulled it off
I was told that the factory vinyl didn't have any protective coating so you need to keep it waxed up real well (same as the paint of course). It was too late for me so I never bothered. For me, the worst bit was the water spots/discoloration from the washer nozzles
