I have painted the dashboard and plastic parts. The product has good coverage and does not shine. It is slightly sticky. It is a black liquid paint. Like shoe paint. Attention. It takes several days to dry, at least 7 days. In my case, even after 15 days, it still leaves black color on my hand. I would only recommend it for external black plastics.

For applications like interior plastics, it does something, meaning it darkens them by a tone and fades any marks. It does not apply well to hard plastics, while it applies better to softer ones. I will try it on tires to see what it does.

Quite a good product for its price. The exterior plastics of my car have faded over the years and when I apply the product, they become dark gray instead of black. Maybe it needs more than one application for better results

For its price, it's good.
It needs some repetitions to work properly.
I give it 4 stars because it is an economical product and I don't expect it to compete directly with a product that costs three times as much

For five euros that the product costs, it is very good. I have tried it, I have painted the plastic parts of the scooter and they have become new again. They had faded from the sun and turned gray from black. The way I applied it was after cleaning the surface well, I applied it with circular motions and after it dried, I wiped it with kitchen paper in circular motions again to give it some shine. If needed, you can apply a second coat. The result is perfect, I recommend it to you!

Cream with black color. On one hand, it penetrates into the small cracks that cause the dullness (bleaching) of black exterior plastic parts and lubricates them to prevent further erosion, and on the other hand, it paints these parts black due to the color. An excellent product that I recommend 100%.
P.S.
The only negative thing is that it requires a little care in application in order to clean the metallic parts that will have been polished, as they come into contact with the plastic and will also be painted black. However, it easily comes off from them.
