Fantastic. I use applicators and sponges to apply it. With the recommended ratio for tires and the corresponding one for plastics and leather, I get an excellent result that lasts without needing large amounts, so know that it will last you for years and does not deteriorate. A friend has had it for 8 years already and it performs the same as new. On the wheels I apply it every 3 washes, and the exterior unpainted plastics with the same dilution for tires easily last 4 months. For the interior, what can I say, I applied it once and never needed it again. What I like most, though, is that it leaves a beautiful satin finish and not the tasteless, overly glossy fake look of other products that are for the same use. It is by far my favorite car care product and, from what I see, it has a very good reputation among detailers.
