Easy to apply to clean dry surfaces
Size: TRIM COAT KIT
Seems to work very well. Made the plastic trim and MIC hardtop on my Bronco look like new. After the two hour cure time it drys hard to touch. Not sure how long it lasts yet.

Why It’s "Pretty Good for the Price"
Style: Trim & Plastic Restorer, 12 fl. oz.
1. Instant Visual Impact The biggest "wow" factor is how quickly it transforms chalky, sun-bleached gray trim back to a rich, factory-new black. It works exceptionally well on bumpers, window seals, side-view mirrors, and even windshield wiper arms. 2. Ease of Use Unlike professional ceramic trim restorers that require surgical-level surface prep, this is a simple "massage in, buff off" liquid. Massage it in: Use a microfiber or foam applicator to work the product into the pores of the plastic. Buff it dry: This step is crucial to prevent the "streaking" that some users complain about after a rainstorm. 3. Deep Cleaning Ability A unique feature of this formula is its ability to remove white wax stains. If you’ve ever accidentally gotten car wax on your black plastic trim, you know it's nearly impossible to remove—this restorer dissolves those stubborn white marks effectively.

A Really Good Product
Style: Trim & Plastic Restorer, 12 fl. oz.
This is the best black vinyl restorer I've used. Some products don't dry completely and run with the first rain, leaving streaks that are unsightly. It restore blackness that lasts.
