Positive: This can easily be on the automotive paint (metallic silver, about 3 years old) apply if a wet sponge is used. The cleaning effect is good. The car should be cleaned beforehand roughly with water and brush. I have the remedy applied in the summer and in late summer again. Now at the end of the water runs still from. You have to achieve a long-lasting seal probably repeatedly apply the remedy. To remove the dried material, I recommend an old T-shirt, so you have enough space to polish down.

Otherwise convincing lacquer finish in succession with long-term effect on multiple dosing.
