Hi, I've just bought a set of Thule wingbars for my A3 saloon. They come with a set of four clear paint protection stickers - I've applied one and the results are horrible. It's a really thick obvious patch, nothing like 3M Ventureshield film which I've used before on my motorbike. I'll only be using the bars occasionally - to get us all to the airport for family holidays. and bike carriers a few times a year. Has anyone else used the Thule bars, are the rubber feed likely to mark the paint? If they do need some protection, I'll maybe try some Ventureshield as a permanent solution, or even just some gaffer tape when I'm going to use the bars, and remove straight afterwards.
