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.

Great product
Style: Trim & Plastic Restorer, 12 fl. oz., Style: Trim & Plastic Restorer, 12 fl. oz.
This makes my 15 year-old car look brand new… And in my experience, it lasts for several months before it needs re-application.
Super easy… Just make sure the car surface is very clean and very dry and there won’t be any rain within a day or so.
