I removed overspray, that is, varnish that was sprayed onto the windows by body shop workers. I sprayed soapy water while rubbing and cleaned it!!! I highly recommend it.

Much cheaper than other clays but it is very soft, personally I didn't stick the residues on me, it just helped them to come off the surface. I believe it is more cost-effective for someone to buy the expensive ones and do their job properly

I have no experience with any other clay of this kind, hence the rating ("good"). It seemed to soften relatively easily and often required kneading. I used it on a windshield with soap (water and dish liquid) as a lubricant. It glided smoothly, did the job, but probably requires more force than what I exerted. I imagine it would work well on metallic parts of a car

Value for money.
Removed paint splatters and various dirt stains from the hood that had fallen from a construction site 2 years ago.
For such "difficult" cases, it requires a lot of patience and scrubbing, as well as a soap solution to make the surface slippery and prevent scratches.
(After cleaning with the polish, it is a nice addition to apply the 3-in-1 Maguiars compound for polishing and waxing).

It doesn't do its job well.
It doesn't shape easily and after a lot of work, it becomes very soft.
I expected better results. It's not worth its 8 euro price.

It is the first clay I use so maybe I am wrong, but it seemed to me that during use it opened very easily. It did not hold its shape so you could make a large surface, resulting in needing to fold it every so often even if it had not collected much dirt. It also required a lot of force to completely remove the stains. However, it does a good job, it just requires patience. I attach a photo with before and after.

It is good, I haven't done the whole car yet, but where I have done it became so smooth as it was in the beginning!

I don't have experience with any other clay bar, I used it on my car, which is in showroom condition, it didn't remove many contaminants from the surface of the car because it probably didn't have many to begin with, there are a few very small dirt particles visible on the clay, I will try it on my everyday car and I will come back. Overall, I am satisfied, I didn't expect miracles, it does a decent job at picking up small contaminants from the surface of the car.
