This clay bar works great at removing heaver contaminates in a timely manner. It is slightly tougher to mold and shape, however I do not find it to be troublesome. This is a great clay bar!

Hardest clay I've seen. Crumbled and was about useless. Old stock or just a bad formula?

I thought my car was pretty clean until I used this clay bar. Definitely recommend. Removed a ton of contamination. Pretty tough to mold but with a little time and warmth it wasn't a big issue.

This is the least enjoyable detailing product I've used. As other's have said, it's hard as a rock and in yesterday's chilly weather it was useless. I had to get out an old McGuire's OTC claybar to finish up a customer's car. I spent the big bucks and bought some more Claymagic from here last night.

Great clay for those hard jobs that have been racking up grit and industrial fall out. 200g isn't enough just kidding this bar is huge and i've used it with several jobs and have some left over.

This bar was terrible. It was so hard that no matter how hot I got it, I could not mold it into a usable shape. On top of that, it started disintegrating when I used it and left clay residue all over the car. I have used the fine grade Clay Magic bars for years and have never had a problem like this. I understand this is a medium grade bar, but it was simply unusable. I'm going back to Clay Magic and I'm not looking back.

This clay bar is the real deal it works on almost anything. I used it on a clients Time Attack car that has been neglected for roughly 8-12 months. However be preparred to polish the marring out. I swear this took at least 1 hour off my claying time comparred to other softer grades I have.
