Worked wonderfully and so easy!
Couldn’t believe how great this worked! I was waxing my car when I decided to wax the bumpers thinking this would protect them from the dry, sunny climate I live in. The bumpers turned white!!! Got the Meguiar’s Ultimate Black Plastic Restorer, wiped it on and they look brand new!!! Lesson to self…don’t wax plastic! I highly recommend.

It works effectively but be patient
This is great stuff but do not expect it to turn really faded out black plastic on the outside of your car to like-new condition after one application. However if you apply this to the black plastic on your car after each wash, it will soak in and turn it into an almost new appearance. And it will last! It works great but be patient.
