Blackfire comes highly recommended and I know a lot of people who use it. It lasts longer and acts better than superguard and it is reasonably priced too.
All you have to do is buy the products yourself then pay a professional valet to apply them. Thats all the dealers do except they charge between £200 and £300 for the privilege!
