The effect is really great! The ugly gray is a great Black, the parts look like new. Also, the application is easy to handle even if you should be a bit careful that you do not smear on the adjacent varnish, which then does not look as nice, especially if you have the car washed fresh.
For durability, the opinions are divided and the right here yes I am also, in part, it keeps for several weeks, but in some cases even a few days. One reason I have not yet been identified. Rain has not turned out to be with me as much shortening factor, the water (and the water of dirt) Pearls of the treated surfaces from and thus causes a slight self-cleaning.
The effect is quite different on the various surfaces, on very slippery surfaces keeps the gel of course not as good as on rough.
So far I have the gel 4 or 5 times and used enough in the tube and will certainly still fairly long (10x - 15x) make do with it.
Order through Amazon ran again, of course well.
