Fantastic product,.... I applied it with a sponge, it darkened and shined... and in 2 minutes when it dried.... it fogged up worse than it was before. The best part came later.... the glasses, bumpers, and side skirts of the SUV got stained, and as soon as our clothes touched them when we got out of the car and when we removed things from the trunk, we became black... all the clothes went to the washing machine, but the black stains remained on them.... Gone are the clothes.... they were thrown away... along with the K2 product. The best for... shoes!!!???

Very good! It made the faded areas of our old car shine again. It restored the black color even on heavily worn plastic. With washes, it lasted at least 6 months before we had to redo the plastics again!

If you want to renew your worn-out plastics, DO NOT buy this product.
It does almost nothing, it's just a black cream that will tire you out and dirty everything around you with zero results. I have tried much better alternatives, regretted buying this one, luckily I got it for a dollar and it ended up in the trash after the first use. I'm also afraid it will dirty my sponge during washing. Stay away!!

I bought it to do the interior plastics (dashboard) of my slk 200 and I can say that it darkened them perfectly! It requires quite a few applications and I recommend wetting the sponge for better application. However, the problem is that:
- Firstly, the result is not completely permanent and you will have to reapply it periodically.
- Secondly, it tends to stain and requires caution to let it dry properly. I believe it does the job it claims, but it is not a permanent paint

Very good as described but needs attention not to paint other parts such as the bodywork because it does not come off

I tried it on the unpainted plastics of my scooter. It takes quite a few hands to make a difference, but it somewhat improves the situation (see photo for before and after). It is definitely something that is not permanent, but needs to be reapplied from time to time. Of course, my plastics were quite worn out.

The product is almost excellent and value for money, it does a very good job, I didn't expect it to be this good. I use it once a month for plastics and after three times, the plastics gained an extra tone. I had never used such a product before, but I would recommend it to my best friend

Overall, it is not the best product for black compared to others I have used in the past. I do not recommend it!

It's not worth it... I tried it on a plastic part of the Agility City 125 scooter, the black interior it has, and it didn't do anything, it was still the same as the rest... I threw it away... Maybe it didn't want me to rub it? Should I have just spread it? I don't think so

Very good for black plastic that has faded on the interior and exterior of the car. It doesn't work on glossy plastics, it's only for matte plastics. Easy to use (you apply it and rub it with a polishing sponge ideally, otherwise any sponge. Not a cloth because it will get dirty). It's worth the money and more! Of course, don't expect miracles like deep scratches or dents disappearing. It simply "paints" the faded matte black plastics.

Edit 12/8/21: In the end, it's not worth it because the color fades with washes. I mean, it's not a permanent solution. Every now and then, you will have to reapply it on the plastics because the color fades with washes.

Very good product that helps in the "restoration" of the color of faded/burned plastics, gives "depth" to the color and a matte finish
