Great product. I used it on a extremely faded FJ Cruiser and it looked like factory afterwards.

I initially applied this to the trim on a Land Rover LR3 to see if it would actually work, and it has. It was applied to that vehicle on October 21, 2020 and, as of this writing, is still going strong. Also used on the windshield cowl and other trim on a Subaru SVX and, again, it has held up very well. My only complaint is that it goes fast; I usually end up wishing I'd gotten a larger bottle. But once it's on, it's on, and that is it. It does not wash off after two rains and never runs. Even though it costs more than normal trim shine products, it lasts much, much longer.

Having had a good experience with several other Gtechnic products, I wanted to give this a try on fairly new trim. I have a bed cover on the back of a 2021 Honda Ridgeline that is going to be up against quite a bit of UV exposure in the south. Honestly I was surprised how it was able to add richness to basically new trim, adding just a bit more darkness.

C4 is effortless to apply and allows for abundant working time. To help make the product go farther, I "procured" some of my wife's make-up pads. The don't hold as much product and that way you can keep the nice Gtech one for another day.

Similar to other's comments, I've tried a wide variety of trim products and cleaners. I especially like not having to remove the streaks that oil or silicone based products leave on the paint after it rains. Would have liked to have tried it on weathered trim. Using a Mr. Clean sponge on old trim works wonders for turning it black again. Make sure to tape the adjoining painted surfaces. Coating it with C4 at this point should make a big difference.
