## Description

Introducing the C4 Permanent Trim Restorer Sealant, brought to you by Gtechniq, the leading experts in car and automotive surface protection. If the trim around your vehicle is looking shabby, tired, faded and old, then give it a breath of fresh air and have it looking like new with the hassle-free application C4 Permanent Trim Restorer by Gtechniq.Premium Trim RestorationAfter time, and with the sun beating down on your car, the UV rays deteriorate and damage your vehicle’s trim, causing it to fade and discolour. Bring it back to life with one easy application of the C4 Permanent Trim Restorer, and it’ll look brand new in no time. Smart Surface ScienceC4 utilises a covalent chemical bond to become an extension of the plastic molecule that it's protecting. It cleverly swaps part of its molecular structure with the surface molecules of your car's trim for premium, long-lasting protection. Unbeatable DurabilityThe C4 Permanent Trim Restorer offers a protective coating of unparalleled durability. Unlike many trim products on the market, C4 is an exceptionally thin (+/- 30nm), optically clear film which restores all but the most faded trim to a “like new” condition, without leaving an unattractive gloss film on the surface. You can expect up to 2 years durability from a single application.Hassle Free ApplicationWhen you purchase from Gtechniq, your C4 Trim Restorer comes with a lint-free application pad for easy application. Thoroughly clean the intended area, entirely removing any fats and oils or previously applied products (for best results use the Gtechniq W5 Citrus All Purpose Cleaner). Apply in a well ventilated area, and then use a Gtechniq MF1 ZeroR Microfibre Buff Cloth to remove any excess C4 Coating. Allow the coating to settle for 12 hours before exposing to the elements, and use within 3 months of opening.

## Questions & Answers

**Q: how can I get more applicators?**
A: You can use makeup remover pads found in any pharmacy or grocery store.  Very inexpensive!

**Q: Will this item work on gray plastic trim?**
A: Hello, It is not like a dye. Gtechniq C4 Permanent Trim Restorer renews the color of trim. Gtechniq C4 Permanent Trim Restorer renews the color of trim, but it does not add artificial gloss. Matte surfaces will remain matte. Trim pieces will look new, not dressed, to give your vehicle an overall newer appearance.Directions:Do not dilute. Apply at a temperature above 41°F (5°C) and out of direct sunlight. If you are 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. We recommend cleaning trim vigorously with IPA (isopropyl alcohol) prior to application. Use the lint free application pads supplied to wipe the coating onto the trim. Because the coating forms its bond immediately, it is very important you remove excess coating from the treated surface and any that has gone onto your car's bodywork or glass as soon as possible. To remove residue, you should use a microfiber cloth and use a light touch, i.e. not like buffing a wax but more like using a chamois on your car.

**Q: How much would the 15ml bottle cover? Would it be enough for a front and back bumper?**
A: A little bit goes a long way...Short answer, I have to say "probably". Long answer...I was able to do all of the trim around my windows as well as the groves for the luggage rack on my SUV, along with the front windshield wiper shroud with half a bottle to spare. So I guess it all depends on the size of the bumpers you're trying to cover. But I would assume you'd be fine.

**Q: Can this be used on interior plastic trim, like a glove box door?**
A: I found an answer from Gtechniq directly: 
"We would recommend that you thoroughly clean the interior (including plastics) with our i2 tri-clean. You may need to use a soft/medium brush to gently agitate away the dirt.

After this, the surfaces should be clean and matte finish. we then recommend protecting with our C6AB matte dash

We do not recommend using C4 on interior plastics"
