I was not satisfied at all. It does not spread well. It requires a very small amount to be applied each time and to make small sections. Then it requires a very good wiping with a microfiber cloth and starting over. If you don't wipe it well and apply it properly, it leaves streaks that can only be removed by washing. Overall, it requires a lot of work and it's not just a "fast finish".
As a result, once you apply it, it looks good. It enhances the color. It does not correct imperfections. Quite the opposite.
I applied it to a part of the car that I had repainted and I noticed the poor job done by the painter, as the metallic color had shadows and water marks.
Contrary to its claim of not holding up at all. It attracts dust and in no way makes the color hydrophobic.
In conclusion, the 2 stars are only because once you finish the second coat, it gives depth and truly enhances the paint (especially the metallic color) but only for almost 1 day.

I used it on a brand new car and I have to say that although I had my doubts at first, it turned out to be fantastic. The car, after a month, has not been washed and it looks spotless, while one time when I was caught in the rain after applying this specific product with just the rainwater and a cloth, the vehicle was easily and quickly cleaned.
