A complete nonsense, I bought it for the scooter's plastics so I wouldn't have to keep applying polish, and the result is zero out of zero. Not to mention that everything turns black.

It did not have the expected result on the black plastics of the scooter, it is like a thick black emulsion with a matte color which did not do the job.

In the photo, you can see the before and after. During washing, the sponge turned black and all the product came off the plastic. Personally, I only recommend Meguiar's Ultimate Black, I have been using it for years and it does an excellent job.

A half-assed product
Luckily I bought the low mg version
It's a mess that smudges and dulls any shine the plastic may have
I applied it with a brush and wiped it off on scooter plastics
Better off just using tape and spray painting with matte finish

I bought it with the prospect of applying it on the external plastics of the car and stop using silicone spray, which did a great job, and I thought let's try the bono black, it should be better for this job supposedly... I followed the instructions but the result was zero... unfortunately, after a few minutes, the supposed black tint was fading away!! It's better to use silicone spray, it lasts almost a month!
