Very Very big clay bar. Worth the money. It works as you'd expect a clay bar would. It picks up embedded contaminants with ease.

My brother and I used this clay bar on his black 335i and it picked up TONS of dirt even though he had it detailed at the dealer about 5 months beforehand. Can't wait to clay it again in the spring and do a full buff and polish.

I used this bar on a new car that had never been clayed and it picked up many particles while not damaging the paint.

First time clay user, but I'm a believer now. My new white hatchback has a bad propensity to get fine clay dirt particles (from the local soil) the do not all come off with a regular washing. I wish I knew why it works, but I know in combination with the slippery dodo juice it gets those pesky specks off my paint without a bunch of marring. Its not the fastest process, but it's saving me from having to do more frequent paint removing corrections

Use it for every car I detail. Works well.

Very happy with this product. I don't really have a ton of claying experience but this one was easy to use, and it did remove a lot of dirt particles from my paint without any scratches. I only used half a bar for the whole car (4-door sedan). Very happy with it!

The picture doesn't show just how this big this bar is, the thing is huge. If your a weekend detailer like me then this bar should last you a long time. It works great with born slippy and white color makes it easier to see contaminates.
