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

First time using and it was simple. First I clean my trim with Gtechnics multipurpose cleaner. My trim was faded from the SoCal sun and after applying it looks brand new! Caution- make sure you wear gloves! Would give the product a 10 out of 10 for ease of use and final appearance.

Like all GTechniq products I've used I get great results. I have applied it to several vehicles from new to old. Its speciality a great product on old, faded trim to restore it to a new look. I also use it on other things like my hot tub cover to keep it looking new. I applied it to the cover nearly 3 years ago and it's still there protecting. I occasionally apply a quick spray of C2V3 as a booster and the cover looks brand new. Where other products would be long gone from sun and chemicals like salt and chlorine, this product is still there protecting your valuable possessions. It's worth spending your hard earned dough on this stuff.

Can't say enough good about this stuff. Used it on my 2005 x5 (which is basically in like new condition) to seal up all the black plastic trim that I KNOW will be fading in time. After applying, it appeared similar to a fresh coat of 303. HOWEVER, one rainstorm later and NO spots or tiger stripes!!!!! FINALLY. I have been looking for this product forever! I swear I'm gonna start putting it on everything. Kid's toys, tools, eyeglass frames, lol! Joking, but it's unbelievably easy to use EXCEPT for the the cleaning prep...which is a complete PITA on old trim pieces that have been soaking up silicone dressings for years. A simple IPA wipe isn't gonna cut it with a 15 year old part with a semi porous surface. I had to soak with tarminator and grease and wax remover (STRONG stuff) and just about everything other than diesel fuel and there is STILL silicone buried deep down in certain pieces. I don't think it'll matter too much though. And the fact of the matter is that this has done what other products haven't been able to do.

Let's face it, the goal of detailing for some of us it to spend as little time as possible on it. I want to get out there, wash, dry and do a quick vacuum and interior wipedown and pretty much be done hopefully within 30 minutes. So I am working on semi-permanent solutions for the time consuming areas like wheels, glass and trim. This one solves a HUGE problem with the trim!

my suggestions are similar to some others' - if possible, a easier prep process would be awesome. and Gtech....how about another couple of makeup pads in the package?! my wife's eye makeup remover pads left lint everywhere.
