Picked up a bottle of this for both our cars. Looking forward to trying it. What I like about it is that you can use it on all plastic trim and even in the engine bay. I emailed TW and they responded that it is safe for engine bay use. I can see this being a fantastic engine bay dressing and exterior trim as well due to the hydrophobic qualities of it. Once the Hyper-Dressing wears off, I'm going to give this a shot under the hood. This weekend I'm going to detail one of the cars and use it on the exterior.
