Great product, it will make your faded and dull plastic trim look new again and water will bead right off. The only issue I have with it is if you apply this to plastic in an area above your painted surfaces and then it rains, it streaks the paint where the water runs down from the trim onto your paint. I applied this on the plastic trim on the top of the box sides on my F150. A few days later my truck was parked in the rain and when it dried, there were streaks down the side of my box.
