Gtechniq C4 Permanent Trim Restorer | Prep, Application and Results

I purchased a bottle of Gtechniq C4 Permanent Trim Restorer to apply to my car to help revive the black plastics. The trim on my car isn’t too faded but I always felt like I needed to apply some kind of trim dressing after the weekly wash to darken it so I picked up this product as a replacement for that process.

In this review I’ll be showing the results after using C4 and demonstrate the preparation and application process.

The trim coating claims to last up to 2 years and left the perfect finish on my car. The trim was darkened but it didn’t leave a shiny or sticky looking surface. I plan to provide some updates on my Instagram (  / autocarehq  .
