Sydney, Australia
I'm really pleased with this product. It goes on easily, buffs up beautifully, lasts a long time and I'm getting a kick out of seeing beads of water sitting on my car on dewy Sydney winter mornings, waiting to slide off with the slightest movement of the car. I also really like the fact that it can be applied to any surface - rubber and plastic trim deteriorates too over time and I believe this product really will help preserve my new-look longer for my outdoor car.
