Mothers Reflections Tire Care. According to Mothers, it's water-based, so it won't dry out rubber over time. It's a spray style tire shine, but if you apply it with a foam applicator, it goes on real nice, no sling, doesn't attract any dust and dirt from the road unless you're driving down unpaved roads.

I used to use those thick sprays and thick gels and while they seemed to last longer and penetrate the tires more, they always attracted and collected every bit of dust and dirt from the road and got all gunky. The Mother RTC is the exact opposite, it just doesn't hold up when driving through the rain. If there's no rain, it lasts a good week until I wash my car. It's great stuff and really cheap for the amount you get, 24 ounces.

Just thought I'd share my opinion on it.
