I have decided, once embellish my aluminum winter wheels and what goes better with a black car as matt black rims? The tire I lost for the procedure and purified according to and degreased with mineral spirits. I then generously taped with masking tape around the rim of the tire. Applying the Spühfolie was simple, but you really have to always just a little apply, otherwise the Spühfolie runs very fast. After several Sprühgängen the result was really worth seeing, you have to look very closely know that the rim has been provided only with Sprühfolie. I drive the sprayed rims now 4 weeks and also in ice and snow, nothing replaces. So, for those who sometimes just want to change their color wheels, I can recommend the system uneingespränkt. Because of the strong odor but one should however make best outdoors or in a well-ventilated room
