I've had the same clay bar for a couple years. I've used it about 5 times. I just keep kneading it getting clean clay to contact the paint, using it w/quick detailer as the lube.

How often do you replace your bar? Is there a guideline for this?

Which clay bars are best, or are they all pretty similar?

If I need to replace bars more often, where can I buy a bunch at a good price?

Thanks,
Dave

 

I have one I have had for probably 6 or 7 years......lol I have no idea how many times I have used it. It still works great and pulls out all kinds of grime!
