I used it on black unpainted plastic of a machine that had faded. It improves it but definitely does not make it look like new nor like the photos in the advertisement. It needs good cleaning and a small amount, otherwise the result is bad. Also, whatever result you get does not last more than three or four months.

Really impressive product! I used it on my car and the scratches disappeared like magic. The color came back to life and looks like new. It is very easy to use, just spray and wipe. Very good purchase for the price!

Once every November after the summer, and it looks like new. A good cleaning before use and a gentle wipe with circular motions using a microfiber cloth! For the money, it’s worth using. P.S.: be careful not to overdo it, just enough to absorb it!

I was looking for a simple and easy solution to restore my headlights... Honestly, I couldn't believe the result. Without sandpaper, without rubbing as the packaging said. I simply sprayed it, let it work, and cleaned it with a soft cloth.
I didn't know how much they had been rubbed when the previous owner cleaned them, so I didn't want a drastic solution, fearing that it would cause irreparable damage to the headlights.
Polytrol is an amazingly simple, fast, and effective solution, I highly recommend it!

It is the best, it restores plastics to their original color and covers small scratches on the car's paint surface. Perfect. I have bought it for the third time.
