After reading this thread I was thoroughly convinced that buying a Meguiars detailer/clay kit was the solution to my cars paintwork ails. I also picked up a bottle of Meguiars Gold class shampoo/conditioner (car wash). 9 cap-fulls and 9 litres of water later, my car was already looking cleaner, more reflective and smoother than it's ever been before. Armorall....... rubbish. I wasn't sure what to expect with the clay. I'm still a little confounded which component, the detailer spray or the clay, is responsible for what is hard to describe in words. This kit seriously needs to be renamed. Something along the lines of "Meguiars MAGICAL clay kit" would be more appropriate. After 2 hours of clay detailing, quite a fair chunk of which was spent on one particularly badly affected area, I was left with glistening, ultra reflective white paint. It's really no exaggeration, it's like liquid glass. I'm guessing the paintwork probably hadn't been treated to a polish or clay for many years prior to my buying the car ;). I'm considering now whether I ought to purchase the other components mentioned in many people's wash/clay/polish/wax regimes. Unfortunately I didn't have time to complete claying the whole car the other day, so i've yet to finish that. Just thought i'd add to the collective positive experience of this product. Best $34 i've ever spent.
