What's "Clay Bar"

[jims-terrano]

Hi guys, I've heard "Clay Bar" mentioned elsewhere. I'm guessing it's some kind of polish or pre polish treatment. Is it as it's name suggests a bar of something that you rub on the paintwork or is it a liquid just like polish.

MattsTerrano has just bought his first car, a nice met black 08 plate polo 1.4 tdi match. It's a great little car but the paintwork is rather tired, I've just given a corner of the bonnet a couple of coats of polish and it has made a difference but no doubt he'll want to give it the works won't he.

PS I need a bigger drive!
