The car plastic restorer is a nano composite coating restores trim to 'as new' condition without altering gloss level.
Strong UV absorption filter and chemical bond ensures maximum durability with a single application typically maintaining a flawless finish for up to two years!
C4 uses a covalent or chemical bond to actually become an extension of the plastic molecule it's protecting.
C4 actually swaps part of its molecular structure with the surface molecules of your car's trim to provide a protective coating of unparalleled durability.
Unlike many trim products on the market, C4 is exceptionally thin (circa 30 nanometers) optically clear film – this means it will not add an unattractive gloss finish to the surface. Instead, it restores all, but the most faded trim to an ‘as new’ condition. It is ideal for new trim, helping to prevent fading.

"This product is brilliant!. Wipe on, wipe off, and it's like brand new. Will be doing all cars with this!"
"Initial observations are this is an awesome product."
"Expensive and difficult to apply relative to other products on the market. We were very careful not to apply too much product but the coverage compared to other products was just not there, with the C4."
"I'have used this product before and its very good"
"All the GTechniq products are great. However, I used this product on the trim on my Chev Silverado and the result was excellent. My Silverado had been coated with GTechniq when new and the Permanent Trim Restorer has extended this protection."
"I researched before buying this product and it didn’t disappoint, the finish is awesome!"
"I was a little skeptical when I first ordered this product and while it has only been on the vehicle for a couple of weeks, the result is amazing and the product does exactly what it says it will do. My faded trims now look amazing!"
"The product as it describes"
"Always turn to GTECHNIQ when I want a quality finish."
"Was extremely content with the results I had come to expect based on other reviews I read. They are all correct, this product is amazing."
