I used this on the plastic trim and bumper on my truck, and I’m honestly impressed with how it turned out. The faded areas came back to a deep, rich black and really cleaned up the whole look of the rear end. I prepped everything the right way by washing it first with an all purpose cleaner, then wiping it down with 91% alcohol. I also taped off the surrounding paint and chrome just to be safe. After that, the application was simple and went on smooth without any streaks or blotchy spots. The difference was immediate. What used to look dull and worn now looks factory-fresh again. It also seems to bond well and not just sit on the surface like some cheaper products I’ve tried before. Overall, this was easy to use, gave great results, and made a noticeable improvement. I would definitely use it again on other trim pieces.

Good product

Size: TRIM COAT KIT

Good coverage. I've had it on for about 10 days, and it's holding up better than any spray product I've used. Not perfect, but none of those streak lines you get with other products. It's been rained on twice so far.

Great product and easy application

Size: TRIM COAT KIT, Size: TRIM COAT KIT

This stuff is awesome. It’s very easy to apply, just make sure the plastic application area is clean but don’t worry about taking too much time to clean the area as long as it’s clean and dry. Made my ‘19 Pilot look brand new.
