Today I used the Displex polish to get the plastic speedometer of my car without scratching. Here it was very slight, but visible in sunlight scratches caused by cleaning well over the years. Many car owners know the problem that today's speedometer glasses are very sensitive and anything but kratzresistend yet. This polish I scored within 10 minutes an excellent result. The speedometer carrier is completely free from scratches and looks like new again. I highly recommend the product. It also requires very little of the polish itself and can easily process this playing with the accompanying polishing cloth. The product is foolproof. However, I can not judge whether it is possible fix and deep scratches hereby. Due to the low grinding performance of the product (which I consider to be a total benefit), this polish for extreme scratch is probably not appropriate.
