Product Description

Gtechniq C4 is not just your regular trim coating, it will bond to your trim restoring it to like new condition with ease! Most trim restorers or protectants are shiny coatings that sit on top of the plastic and they only provide temporary shine and color restoration. C4 actually swaps part of its molecular structure with the surface molecules of your car's trim! This allows the C4 to keep your trim looking brand new for up to two years! Use C4 on trim, weather stripping, plastic mirrors, battery covers, hoses, etc. If you are looking to restore your trim to like new condition grab a bottle of the C4 Permanent Trim Restorer today!

Application Information
  • Do not dilute
  • Apply at a temperature above 40 degrees F and not in direct sunlight
  • If applying indoors ensure that there is adequate ventilation and wear protective gloves
  • Ensure that the surface to be coated is entirely free from fats/oils or previously applied products
  • Use the lint free application pads supplied to spread the coating onto the trim
  • Because the coating forms its bond immediately it is very important to remove excess coating from the treated surface and any that has gone onto the vehicles bodywork or glass within 5 minutes of application
  • To remove residue use a clean microfiber cloth

Professional Detailer Reviews

If you are wanting a product that is extremely easy to use that will darken and protect your trim for years, not weeks or months then you will certainly want to give Gtechniq C4 a try.

Applying Gtechniq C4 Permanent Trim Restorer

I bought a nine year old used car and wanted to restore the faded trim. The C4 did a very good job of bringing the black back to the faded trim without making it overly glossy. I only prepped a few areas as I didn't know how far the C4 would go. I still have 3/4 of the bottle left so I will be able to finish all the weatherstripping on my car. As long as the coating holds up durability wise I would say this is a very good value.

Great product - love all of Gtechniq's coatings. Can't speak on longevity as I just finished applying it to the black trim of my motorcycle.

I have a dark grey metallic Subaru STi. I was getting tired of the whitish fins on the side where the side-view mirrors. The sun really took its toll on them. I bought this off a 25% discount sale from DI. I applied this and left it on for 5 mins. I wiped it off and applied another coat and left it on. I did that 3 weeks ago and I was amazed with the results. I thought it would fade off like all the other products do. I applied this 3 weeks ago and it looks brand new still. The water beads up on top of the surface after it rains. It is def an awesome product. I decided to do the entire door trim with it, some plastic pieces in the front grille area and the rear bumper area where I have black plastic. I still have half of a bottle left. This stuff goes a long way and it's totally worth the money. Some people see the price and say "That's too expensive..." which is true. If you have any sort of black plastic pieces that you can tell the sun took its toll on it, buy this. You won't be sorry.
