Gtechniq - C4 Permanent Trim Restorer

Gtechniq C4 utilises a covalent or chemical bond to actually become an extension of the plastic molecule it's protecting. Not to be confused with much weaker electrostatic bonds used by, amongst others, ptfe based polymers Gtechniq C4 actually swaps part of its molecular structure with the surface molecules of your car's trim.

What this means is that you now have a protective coating of unparalleled durability. Unlike many trim products on the market Gtechniq C4 is an exceptionally thin (circa 30nm) optically clear film which means that it does not add an unattractive gloss film to the surface instead it restores all but the most faded trim to an as new condition. You can expect approximately 2 years from a single application.

How do I use this product?

Gtechniq C4 Permanent Trim Restorer is a relatively easy product to use but correct preparation and application is essential. Take a look in the resources section for a pdf and take a look at the youtube below showing you how to apply.

Available in 15ml & 30ml bottles

“I used C4 on the faded front fairing of my Honda CBF600. Now it's a bit darker but I expected much better results. The fairing was thoroughly cleaned before applying C4, followed by degreasing with CarPro Eraser. The poor result could be caused by low temperature after applying C4 (just a few degrees) but I am not sure. I am a bit dissapointed.”

“As others have said, seems a very good product, what there was of it! Not quite enough for my Volvo XC70 which was a shame as at this price, I cannot justify two bottles for one application. Would have given 5 stars if a slightly larger bottle.”

“Good stuff but expensive. A tad cheaper and 5 stars would have been awarded.”

“Having tried various trim products of both wet-look as well as matte finish varieties I stumbled across this product. Whilst its easy to be put off by the price considering how small the bottle is don't be, you use literally drops of this on most trim panels as a little will go a very long way. Application is simple, thoroughly remove any previous wax or product on the trim piece, then apply using the provided cloths and then buff off using a microfibre cloth, that's it. The panel will return to its original look, not shiny but also not dull. Highly recommended and the best trim product I've used to date”

“Excellent stuff, I just used a microfibre cloth to put it on & remove, fantastic results. A little disconcerting about the price against the size of the bottle but definately worth it. Recommend to list everytging that requires C4 & do all at once as you have to throw away the microfibre cloth after use.”

“Watched a video of how to apply this on the gtecniq website and thought it looked too easy but it was so simple. You only need a couple of drops, wipe on and then wipe over and it's done. Looks brand new... Excellent product!”

“I don't know why I was so surprised that it worked as well as everyone said it would, but I was. Everything you've heard is true. Its obscenely easy to apply & its horribly effective! No chance of telling the Mrs it took hours of backbreaking arm straining effort to apply. You put it onto a pad & wipe it over & yer done. It leaves plastic with a "factory fresh" look, not shiny, not sticky, not nasty looking. Just nice black plastics.”
