Every time I've purchased a car and they offer the paint protection etc, I look at them dumbfounded and go "Oh! You mean that the car's paintwork out of the factory isn't good enough and still needs this? I might keep thinking about my decision to buy." I's amazing how they back peddle on the offer.

So car companies spend hundreds of millions of dollars in research and development to build and paint cars that can withstand the salted roads of Europe and North America. Then the dealer sells you on the idea of improving it by getting some 16 year old to rub a bottle of $20 liquid over the paint and charge you $300. Oh please.

If you'd like to do a similiar thing, a go over with a clay bar detailing kit and then Meguiars NXT. Lasts months and car looks like it's coated in glass.
