I have seen a lot of products over the years that say one thing and deliver another, but I have actually done the leg work on this prouct even on my RS6 and it actually does what it promises. I know the person who imports this polish from Germany and I told him he would have to give us a discounted price if he wanted to sell it to us. I dont know if I'm violating any forum rules so before I post the flyer will somebody school me?
