cypprim, I can get one claybar to last for a good 3 full car's with enough lube. Cutting it into thirds is what I do. Tree sap breaks down the claybar? Never seen that in any of my cases. No shit about dropping the claybar and not using it, who the **** are you? Einstein? ****ing idiot, thinking I wouldn't know that. Haha, you'd hate to see my car. I can guarantee it's contamination free, with no swirl marks, super glossy, heavily wax protected and very slick due to a good caranuba wax I use. BIATCH. Damn, I hate ****ing stupid good for nothing noobs like you.
