all clay bars are the same I use a zaino, but you can pick a mothers clay bar kit up at pep boys or krage for like $15-$20.
the mothers comes with it's own lubricant but from what I've heard plain old dish soap works best(the same thing that zaino recommends, dawn, because it fights grease, and eats wax) you get a little spray bottle and mix some dish soap and water maybe 20 to 1 then wet down a section of the car and rub the clay bar or it, ever foot or so you fold the clay bar and smooth it out so that the crap you just removed isn't draggin on the paint, then you go over the same part of the car again and then fold the clay bar again, then move on to the next section. Do that to the whole car, and you won't believe how smooth your paint will feel, better than the day you bought it. a good test is do a little section that isn't noticable that much then dry it and rub the back of your hand over it then rub the back of your hand over a part that hasn't been done. You will be amazed. Anyhow it took me about 4 hours of sweating my nuts off to claybar my whole car, but the results were incredible. When I waxed it I was in awe. I never thought my paint would look that good. It honestly looked better than the day I bought it.
a side note, before you do this, wash your car the best you can with a real thick dish soap mixture. Dirt on the car when you claybar can scratch the paint. Another tip, if you drop your bar on the ground, just throw it away heheh.
