Yes, this stuff really works! (Read Review)
The short: This works exactly how its described and brings back the factor color to your sun faded plastics. This is not a temp fix which fades the next day (like tire shine), this really does restore it. The long: I actually hesitated on buying this product because of its size and cost. I bottle of trim restore at AutoZone or advance auto is like 8 bucks and comes in a 12 ounce bottle size (350 ml) Quick math would put that at around 3 cents an ounce, This C4 product is 45 dollars for 15ml is around 3 dollars an ounce, literally 100 times as expensive. Well, the thing is I have tired those car shop trim restores before and quite frankly, they are only really good for showing off your car that weekend, or posting it for sale… as the restore last a week tops. In some cases, (with armorall) I found it actually looked worst after some time then before I applied it. Needless to say, I was actually looking for a more permanent solution and didn’t want to go the auto shop route again and found this recommend on a forum, with the post saying this was the only product that actually worked. I saw the results and decided to try it. Prep: First wash your bike or car off completely with a mild soap and water mix, for me It was my bike and I just used a large bowl with a soap water mix and a wash cloth, (this took 10 minutes) Do a quick rinse with some clean (no soap) water and dry it down (5 minutes) Then take some rubbing alcohol and put it on a small cloth and go over all the plastic you are going to restore. If you haven’t used alcohol for cleaning, don’t worry this is one of the few strong cleaning products that actually does no damage to anything (paint or plastics) and evaporates clean. (This took another 5 minutes) Once all cleaned up, put on some gloves and pour just a few drops on to the supplied pads and beginning wiping down one plastic area with it. Be sure to stay just on the plastic and get into all the edges completely. Anything you miss will be obvious you missed it so take your time. This took about 10 minutes each side of my bike (20 total). After your done do a wipe down with the same pads supplied to make sure you don’t have any streaks and add additional to areas that you may need more. For me it was truly one coat and done. I was able to do my full fairing BMW with less than 1 bottle of the 15ml (probably used about 10ml’s) From the time I opened the package to when my bike was completely finished was 40 minutes. If you use up the pads (I only used 4 so I still had ones left over) but if you do, you can use makeup remover pads, just make sure they are just the pads with no remover product applied, they are usually like 5 bucks for 100 of them and can get them at CVS or any grocery store. Once all applied keep it out of the rain for a day and let it sit overnight, next morning your good to go. Its been 2 weeks now since applied, and though I know that isn’t long, its quite clear that it looks exactly how it looked after I applied it to weeks ago. This is already quite noticeably better than any other product I have ever used for restoring. Couple quick points: This is a clear product that simply restores any color back to its original finish, so ifs grey, charcoal, or black it will bring it back to like new. This works on faded and spotted areas as well as sun streaks and over washed areas, which if you’re the type that washers you bike or car regularly you will know that it starts to fade the plastics faster than even the sun does. Last this really works but take your time and prep and apply it as I mentioned, don’t rush and you will have a great looking product. Hope that helps!

Best Product on the Market
I used this product to revive the plastic grille/trim on my rear bumper. It seems to work really well, and you don’t need much product to get the job done. I have a lot of extra now. Pro’s: •Permanent bond, long term resilience •Easy to apply •plenty of product •comes with applicators Cons: •the applicators kind of suck, and are not lint-free. I’d recommend using a foam brush from the dollar store to apply the product to avoid getting lint bonded to your trim. I’ll update my review if the product doesn’t last as long as advertised.

Amazing
Works Amazing. Easy to use. Has lasted a good while. Brightens your black exterior trim perfectly. The only fault is its a very tiny amount you get. But it did my whole vehicle. I definitely recommend it.

Not enough liquid to finish the car
Works exactly as expected and has not lost shine in a year. A little frustrating because we’re about 2 ounces short of doing the whole car or they would’ve got five star stars

super easy to apply. no oil. no residue. better than new!
saw a ad for this a purchased a small bottle. wasn't too sure about it because of the size of the bottle. this stuff is magical. I have never bought a product with this result. no oil no stain. it really does look amazing. I'm sold for life on this one. no words can describe how much it works. it's just smooth and easy to apply. if people don't try this product they are not getting it good like this stuff. better than new? absolutely!

Pay the price cause it’s worth it
This stuff is good. Did the job better than expected? Lasted a long time held up in the sun in Florida buy it again it’s a little pricey, but it’s worth the money.

Don’t waste your money
Garbage. Not only is it overpriced, but I have a 2022 Highlander with plastic around the base and it barely covered it. It lasted a week after boasting great lengths of time.

If you are skeptical, you need to TRY it yourself!
Very skeptic and reserved on this product. But after reading reviews and seeing posts about it, photos, etc. I was somewhat hesitant on paying that price for it. But after using it only ONCE and might need to reapply to keep it up after 6 months of applying, it restored my dull black plastics and has shine. Application and ease of use is too easy. Make sure to prep the area (wash/clean surface, painters tape areas where it could touch i.e. glass, and use small applicators (make up pad worked perfectly). Did this on my 2020 Dodge Charger Scat with honey comb areas and trim faded. Recommend this product to anyone who is skeptical. You won't be disappointed.

Really works.
Been a month now since I applied it and after several washes. I wish I could share the before and after photos. No more of that chalky texture and water slides perfectly even off it.

Hat fast meine Teile zerstört
Der letzte Schrott, jedenfalls bei mir. Ich habe mir das Coating für die Plastik Windlaufabdeckung geholt, um diesen ein bisschen extra UV Schutz zu verleihen. Angewandt wie in der Anleitung beschrieben und 14 Stunden "ziehen" lassen. Nach diesen 14 Stunden war das Ergebnis: fleckig und extrem glänzend. Ich konnte das Coating einfach mit etwas Isopropanol wieder abwischen. Erstaunlich. Nun habe ich 1 Stunde die Teile poliert und bin da wo ich vorher war. Nur 40 Euro ärmer.

Car trim colour restorer
Good stuff. Doesn’t work magic but if it’s just colour faded trims this is great at darkening.
