What will it do to the gray color, turn it black?** A: While this product does have color enhancing properties, it will not change the color. If in doubt, simply test a small, hidden area to see if the end result is acceptable. Hope this helps! **Q: can this be used in combination with 303-aerospace (UV) protectant for plastic/powdercoated outdoor furniture, or is it duplicative?** A: Unfortunately, 303 Aerospace Protectant is not compatible with this product. Thanks for the question! **Q: Can I apply a ceramic coating after applying this to any exterior trim?** A: I did it on my plastic trim and the metal that is textured metal on my tri-fold bed cover on my f150 and later on the same day it got dusty but after I hosed it the next day you can see it doing it’s thing and has lasted a few months since I applied it and my truck is always outside never in a garage. So I believe so. **Q: Can this be used on car interior** A: The Trim Coating is best used on exterior plastic, vinyl, rubber, etc. For the interior dashboard, interior door coverings, etc. I recommend the 303 cleaner followed by application of the 303 Aerospace UV protectant. Have used My car is 12 yrs old and the interior still looks new. ## Customer Reviews ### ⭐⭐⭐⭐⭐ best trim coating! *by M***O on July 19, 2026* I have yet to find a better product ### ⭐⭐⭐⭐⭐ It looks great! *by F***T on May 31, 2026* I got this stuff to bring back the color on my 219 Colorado.

We will see how long it lasts compared to "regular" 303 protectant. ### ⭐⭐⭐⭐ Works But Leaves Oily Residue *by S***C on June 6, 2025* As directed, it is a clear semi thick oil type of liquid for use on any black plastic or rubber tirm. It immediately brings a solid deep tone to where it is applied. On certain areas of my truck, I used mulitple coats to restore trim. a "mobile detail professional" left some kind of white residue or accidentally bleached (he had used acetone to remove a magnet that stuck to the paint after a year) every single black surface of my 2023 4Runner. he was hired to do a ceramic coating, which he claims to have done but what i believe he does instead is show owners the bottle and pretends to have run out of the cheaper type and claims to have used the more expensive version hoping for a tip. he prepares the surface, not with a clay bar, but rather a waterless wash, then another chemical to remove swirls, before applying ceramic. so it is destined to fail prematurely. while it lasts, it is VERY shiny, which is a bonus for blk which always looks dirty. but to be left with a white waxy looking reside on every black surface from roof rack to running boards is unacceptable. my 2 yr old vehicle looks 10yrs old now. i tired mineral oil, armor all, Honda detail spray, Goof Off, giant pink erasers, among MANY other products. nothing, and i do mean nothing has removed it. most simply cover it up for a week. so this pours out easily but is an OILY type of product and while this restore did work semi well on most of the black, on run boards, despite removing the coating as directed (wiping with another microfiber cloth) it left a greasy residue that transferred to shoes and now the brake and gas pedals. b/c it left a slimy coating, dirt has also collected on it. so i will not purchase again for surfaces that are walked on, such as running boards or cargo pad. below images: windshield cowl before during, running board during, before, and after, cargo pad before and after, after run boards - what the restore did not fix - and a few other before bits ## Frequently Bought Together - 303 Products Graphene Trim Coating – Hydrophobic Graphene Coating – UV Protectant Coating – 6 Months of Protection – Darkens and Renews Plastic Trim – Non-Greasy – 8 Oz (30249) - 303 Products Graphene Nano Spray Coating - Enhanced Gloss Finish & Depth, Water Repellent Spray, UV Resistant, Helps Prevent Scratches, Beyond Ceramic Coating for Cars, Car Detailing Spray, 15.5oz. - 303 Products Automotive Protectant Spray - Helps Prevent Fading & Cracking, Repels Dust, Lint & Staining, Superior UV Protection & Restores Lost Color, Exterior & Interior Car Cleaning Supplies 16oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/496538913-303-graphene-trim-coating-8-oz](https://www.desertcart.jp/products/496538913-303-graphene-trim-coating-8-oz) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-23*
