The best 30 euros I have spent on my car.
White car of two years, it had small rust marks on all its exterior metal surfaces, which no matter how much I cleaned the car, they wouldn't go away.
It made them disappear very easily, truly a magical product.

All the paint gun paintballs that had stuck to the entire surface of the car were removed.

As clay is relatively hard.
It requires mandatory soap from dish soap (better than clay lubricants).
It will leave marks if the dirt is deeply embedded in the paint, which can be removed with a coarse compound.
Also, if the car has pronounced orange peel (which it shouldn't, but okay), it will rub off the tops of the pimples and it will seem cloudy, fear not, you can polish it.
If you want to soften it, put it in water at a maximum of 40 degrees and maybe in your sprayer with the soap, use warm water so that it stays soft (of course, it will remove less that way).
Anyway, it's a good clay and the 3M brand has a high dirt capacity, so I recommend it.

Very good and sufficient quantity of paste. It requires a lot of force to shape it and soap to make it glide smoothly.
