How many time can I use the same clay bar ?
I use it once then chuck it. It traps a lot of dirt and grime on it. You can get a pack of them from NAPA....
I'd call that wasteful (or either you're not cleaning the car well enough before using it, or, you're dropping it).
You should be able to do an average sized sedan about 6 times before its time to replace it (as per Mother's clay bar recommendations, if I recall correctly).
Although the NAPA recommendation might be something I'll look into...
