These are a very easy to use stick on solution for worn button surfaces on your dashboard audio or climate control units. I only had three buttons that showed any wear but they were just bugging me. I found these to be the solution I needed. Two of the buttons looked to be damaged by a caustic substance spilled onto steering wheel control buttons. The other appeared to be from over use of the climate control fan button. But as you can see from the before and after photos these did the trick. Very easy to use and should last a good long time. I'm extremely happy that all controls now look as new! And should I ever need to replace the same ones, they whole sheets are very reasonably priced and fit fairly well.
