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

From The Label


Ensure your trim is thoroughly clean and free from any other product. Dab product onto applicator pad, apply and remove residue immediately with a Gtechniq MF1 ZeroR Microfibre Buff Cloth (or similar towel like the DI Microfiber All Purpose Towel).

This stuff is crazy good. Prep work is key as in anything we use. Once the surface is properly cleaned, I use an applicator pad with a few drops of this and wipe it on, I let it sit for a few seconds and lightly wipe with a clean micro to eliminate smearing. The results are incredible and will add thousands of dollars in value to the vehicle.

Applied C4 to the wife's new car on 12/28/2013. Very easy to use and A LITTLE GOES A LONG WAY!
Just be sure to clean the trim surface you are about to coat. I used an APC, 50:50, mix three times then a final IPA wipe.
Dries quickly once applied just follow the instructions. Will post in the future with results.

Update: The car has seen various winter weather along with road salt and the finish is still as good as just applied.

Pros of this product, id have to say that it is simple to work with and beads water. Cons are that if you do not wipe off the excess on the trim it will stay glossier than the rest. My experience using this was super easy. Used an applicator, gloves and an all purpose micro fiber towel. Nothing to fancy and my results were like new. The trim on my 2006 subaru sti was faded and just about 10 years old. I never really gave my trim much attention cause other products out there never really last. I must express prep is key when you apply this product or any other product. You must clean the trim very well to remove dirt oil grease or whatever is on the trim and then use an ipa to ensure it is clean. If your towel is coming up black you must keep cleaning this is not a cheap product and you want to do it right the first time so clean well and this product will do what it claims extremely well.
