Not worth the money. I would suggest you keep your money in your pocket.

You can buy the stuff yourself and do it for a fraction of that price. Also, you will know it's been done proprerly then. If the dealer does it the job will probably be given to someone who's there on work experience.

Salesmen like to talk you into having it done; they get a nice commission on every treatment they sell!

£50 buys you some very good cleaners, polish and acrylic sealants which will do the job as well or better because you'll do it properly and the dealer won't always. Should last you five years or more doing it twice a year, spring and autumn.

Teflon maybe in the paint, its getting to the point we wont even need to clean our cars,bit ott me thinks

It's not Teflon. The application is made on top of the paint at factory as an optional extra. It's a formula invented by a U.S. company.

Teflon was meant to be a joke but the wink didnt work, they only use teflon in engine additives ;-)
